This is pgx v0.0.15. It contains a number of fixes and new features.

Please make sure to update the cargo-pgx subcommand to v0.0.15 by running:

$ cargo install cargo-pgx

New Features

  • Returning a Vec<T> where T: PostgresType from a #[pg_extern] function is now supported

  • When building pgx iself, failing to specify the Postgres version feature (ie, --features "pg12") now results in one compilation error instead of thousands.

  • pgx's schema generator now applies a search_path setting to every #[pg_extern]/#[pg_operator] function it generates. This change now requires that extensions be relocatable = false. This is set in the extension's .control file and needs to be updated as the previous default was true. Failure to do so will result in an error during pgx's schema generation phase.

  • Postgres versions are updated to the latest point releases. If you'd like to also upgrade to those, simply re-run cargo pgx init. Your existing databases will be preserved.

  • cargo pgx test now has a --release flag.

  • Invent cargo pgx connect pgXX to connect to the specific Postgres instance without compiling/installing an extension.

  • New #[derive(PostgresEq, PostgresOrd, PostgresHash) traits for automatically generating semantically equivalent Postgres operator functions, along with operator classes/families, allowing such types to be used in Postgres btree and hash indices.

  • The extension_sql!() macro is validated at compile time.

  • Safe support for Postgres' Shared Memory and LWLock system. We currently support custom types (Copy/Clone), types from heapless, and standard Rust atomics -- allowing for safe usage of these types across Postgres backends.

  • The _PG_init() and _PG_fini() functions now only need #[pg_guard] applied. It is no longer necessary to apply #[allow(non_snake_case)] to avoid compiler warnings.

Fixes

  • pgx's schema generator now processes .rs files in alphabetical order to
    ensure consistency across platforms/filesystems

  • Adjust the order in which DDL objects are generated

  • Functions behind #[pg_guard] are no longer allowed to be called by threads. Doing so will result in a panic!(). This ensures, at runtime, that function calls to Postgres only happen on the main thread. This check is disabled in --release builds to avoid runtime overhead in such builds.

  • panic!()s from threads are logged to stderr (which should go to your Postgres log file), rather than being converted into Postgres ereport(ERROR)s.
