I had the same error yesterday. It appears that writing on some folders or creating symlinks are problematic in WSL right now.

jwsloan · 2016-04-14T11:04:21Z

Has anyone found a workaround for this?

yjwong · 2016-04-23T17:53:36Z

Seems like there's no proper System V shared memory support at the moment.

Still waiting on this.

One of the things holding me from developing on windows with Ruby.

the-ult · 2016-06-17T20:54:53Z

So you don't get an error while installing postgres on WSL?

Which version of postgres are you using?

Or do you mean the combination of postgres on Windows and Ruby on WSL works great?
I thought programs on Windows are not accessible from WSL.
So I figured, the same would go for a rails server using postgres...

the-ult · 2016-06-17T21:06:49Z

Thanks, didn't think of it that way.
Gonna try it out.

Op vr 17 jun. 2016 23:05 schreef SRGOM notifications@github.com:

The combination. You don't use postgres as a process, you access it over a
port so there should be no issues there

alexfromvl · 2016-06-22T06:53:41Z

I got the same error on a new release - build 14367.rs1_release.160613-1700. Can anyone find a solution?

threebyeight · 2016-06-22T07:42:20Z

Someone has to implement that call to the kernel.

glebovsky · 2016-06-22T07:44:19Z

Hi!

Can someone please describe how to connect to postgres on the host, like @SRGOM mentioned?

Thanks!

jwsloan · 2016-06-22T11:39:01Z

I am successfully connecting my Rails app running in WSL to Postgres on Windows. I don't recall doing anything special to make that happen.

glebovsky · 2016-06-22T13:29:07Z

@SRGOM Thanks! Just tried it and it works perfectly.

alexfromvl · 2016-06-23T07:59:41Z

@SRGOM Thank you. When installing Postgres on Windows normally. You can consider this alternative, until they make proper implementation in bash.
Recipe for those who have problems:

Set Postgres for Windows.
Start the server Postgres.
Connect to the database server, as is usually done in the unix;

threebyeight · 2016-08-03T06:19:04Z

I can think of at least a couple of reasons I don't want Postgres running on Windows and one involves just not wanting the service constantly running in the background when it can be turned on/off by starting/stopping Bash; having to actually open up the services applet to shut it off/turn it on is kind of inconvenient when I'm only using it for the purpose of development. Two, I read that developers were talking about ending support for the Windows port on a mailing list because it's difficult to maintain.

Until this is fixed, I'm sticking with my virtual machine.

threebyeight · 2016-08-03T10:57:10Z

I think that, for me, it's just a matter of convenience. Right now, I unpause my VM and go. If I wanted to start using Bash I'd have to start the Postgres service and then start Bash because I would prefer not to have the service running in the background. Call me paranoid.

bouvyd · 2016-08-03T13:19:00Z

I have Ubuntu 14.04 and Windows 10 on the same machine, and frankly my stack is waaaayyyyy slower in Windows 10 with the server code running in the shell and postgres installed on Windows.

I'm not sure yet what could be the cause of this:

windows psql install being generally slower than its unix counterpart
extra network layers caused by the fact that I can't connect to psql through a unix socket
something else entirely (maybe the shell integration layers themselves)

But I sure as hell would like to compare, because the difference is extremely noticeable.

pavelbulanov · 2016-08-03T14:47:16Z

@dbo-odoo, it's unlikely related with postgres, unfortunately - it more looks like overall slowdown in some kind of operations inside bash

if possible, try doing kind of hack for your app to not use db (use static stubs instead) and measure

for me, starting rails server (which doesn't do any postgresql queries) takes like 5-7 secs, comparing to 1-2 secs inside Ubuntu virtual machine (on the same hardware and with lack of resources for VM)

aseering · 2016-08-03T16:01:51Z

@dbo-odoo -- curious, can you quantify "extremely noticeable"? For you, is that like 20% slower? 100x slower?

bouvyd · 2016-08-03T17:15:33Z

@pavelbulanov yeah that's not something I'm gonna be able to do easily, but if I do have time i'll test it

@aseering I'd say along the lines of 2-4x slower (as a gross estimation)

If I do some benchmark I'll post them here.

alexssung · 2016-08-03T19:42:27Z

I'm also experiencing significantly slower start up times for rails server. The report below shows benchmark results for bash on Windows, and apparently File IO performance can be over 6 times slower than on Ubuntu!

http://www.techrepublic.com/article/windows-10-how-well-does-it-run-ubuntu-bash/

fpqc · 2016-08-09T17:20:35Z

@alexssung yep, I believe @russalex said that the file i/o is the main bottleneck in his //build/ conference presentation

valorad · 2016-08-10T01:56:20Z

I experienced the same issue, trying to install PostgreSQL 9.5 for my django. There was no error reported when installing, but something went wrong when creating database superuser and templates.

pavelbulanov · 2016-08-10T13:35:59Z

@FqPc, do you know if i/o slowdown is relevant to bash working with both file systems, VolFs and Windows f/s via mnt?

fpqc · 2016-08-10T15:29:45Z

@pavelbulanov the best place to ask would probably be in a new thread and ping russalex in it

russalex · 2016-08-10T16:49:29Z

Happy to answer this one here.

The file system performance hit happens on both VolFs and DrvFs. VolFs may actually be slightly faster in some situations simply due to the amount of caching we do there, but in most cases the perf will be very similar between the two.

Throwing a quick shout out to @SvenGroot's excellent file system blog post here. It does help explain a lot.

diwu1989 · 2016-12-18T09:08:45Z

You probably don't want to run Postgres inside BashOnWindows anyways because of IO performance.

It's just plain simpler to run https://github.com/garethflowers/postgresql-portable on Windows side and connect via TCP on linux side

olinbg · 2017-01-10T18:37:34Z

@colinrubbert This worked great for me, thanks.

Very minor edit - I think you meant "postgresql-client" not "postgres-client"

colinrubbert · 2017-01-10T18:41:35Z

thanks @olinbg I will fix it. Must've just been speed typing 😄

steveklabnik · 2017-01-12T00:59:14Z

Came to this issue, found the workaround, works great 👍

arjennienhuis · 2017-01-15T20:33:34Z

With build 15007 postgres works. The shared memory works.

What doesn't seem to work is the UNIX socket.

It starts and you can connect to it using TCP. To log in you first need to edit pg_hba.conf and enable 'trust' for 127.0.0.1

wbrianwhite · 2017-01-16T03:52:22Z

This bug isn't assigned to anyone, but can be closed per the above comment.

https://blogs.msdn.microsoft.com/commandline/2017/01/09/bash-in-windows-insider-build-15002-many-fixes-but-a-couple-of-bugs/

Along with support for the following shared-memory syscalls which are widely used by a number of Linux tools including PostgreSQL.

shmctl
shmget
shmdt
shmat

arjennienhuis · 2017-01-16T07:32:04Z

Is there a separate issue for the UNIX socket not working?

sunilmut · 2017-01-16T19:11:31Z

@arjennienhuis - Thanks for the validation and the post. Can you provide more specifics with what is not working with UNIX sockets? Targeted repro steps are very useful.

$ strace psql

fcntl(4, F_SETFL, O_RDONLY|O_NONBLOCK)  = 0
fcntl(4, F_SETFD, FD_CLOEXEC)           = 0

getsockopt(4, SOL_SOCKET, SO_ERROR, 0x7fffca92ae5c, 0x7fffca92ae70) = -1 EINVAL (Invalid argument)
...

and in Linux:

socket(PF_LOCAL, SOCK_STREAM, 0)        = 4
fcntl(4, F_SETFL, O_RDONLY|O_NONBLOCK)  = 0
fcntl(4, F_SETFD, FD_CLOEXEC)           = 0
connect(4, {sa_family=AF_LOCAL, sun_path="/var/run/postgresql/.s.PGSQL.5432"}, 110) = 0
getsockopt(4, SOL_SOCKET, SO_ERROR, [0], [4]) = 0

The source says:

			/*
			 * Write ready, since we've made it here, so the connection
			 * has been made ... or has failed.
			 */

			/*
			 * Now check (using getsockopt) that there is not an error
			 * state waiting for us on the socket.
			 */

			if (getsockopt(conn->sock, SOL_SOCKET, SO_ERROR,
						   (char *) &optval, &optlen) == -1)

@arjennienhuis - Thanks for collecting the trace and dissecting it out. Makes the analysis very easy. Good news is that the support for SO_ERROR for unix socket was recently added (thanks @benhillis), but the fix is only available in our dev branch. It is making it's way to the release branch.

arjennienhuis · 2017-01-17T21:51:38Z

#1354 mentioned that. Thanks!

arjennienhuis · 2017-01-29T22:01:29Z

This doesn't work with 15014. Any idea when the fix will be released?

sunilmut · 2017-01-31T00:44:59Z

Support for SO_ERROR for unix sockets came in 15019. Can you try with that build?

StephanMeijer · 2017-01-31T07:33:41Z

Same issue here with PostgreSQL 9.3.15.

I'm still "Initializing updates"... 😞

everything seems to work on 15025
