Full Changelog: v0.2.1...v0.3.0-alpha.1

v0.2.1

Improvements

• NULL Support: NULL can now be safely inserted into vector columns without error. They will be skipped during pgvecto.rs index creation, but exist in the table. A query on a vector column will never return a result containing a NULL.
• Signal Handler Fix: Now we use SIGQUIT instead of SIGHUP to trigger a peaceful exit, since SIGHUP is defined as configure reload by Postgres.
• Upgrade Script Refine: Due to some symbol renaming, the upgrade path from v0.1.10 to v0.2.0 is broken. Users can now upgrade directly to v0.2.1 if they are currently using v0.1.10.
