[pg] add migrationsTable config support for migration

[g3r4n]

With mysql migrations you can change the migration table name, this PR add support for migration table name change for pg.

For context I'm trying to add dynamic schema support to my application. This can be achieved easily if we can change the migration table. I'm using the database connection to specify, through the search path, the schema to do the migration on but I need to have separate migration table for each schema.

Thanks for PR!
I think you need to add 1 more pg driver neon-http and and migrator changes there as well.
Also would be great to make drizzle schema customizable same as table name for migrations

@AndriiSherman done !

I just thought about one more addition I would like to have in this PR before the actual merge. I think we need to add a few tests for migrations. I will guide you a bit on what and where should be added:

Here is a test example for migrate(). In this test, we run migrations and then try to query the tables that are in the migration script. If no errors occur, it means migrate() worked as expected.

It would be great if you could create another set of tests to check:

• Custom schema is working.
• Custom table name is working.
• Both custom schema and custom table name are working.

You can check it by querying the specific custom table and custom schema to see if those tables are created and not empty. Additionally, you can query tables from the migration script.

It would be great if you could add it for:

• node-postgres
• postgres-js
• vercel-pg
• neon-http

@AndriiSherman I've added the tests.
I was unable to run them for vercel/neon because you can't test it using a local docker DB.
