v0.2.0-beta.4

This is pgx v0.2.0-beta.4. It resolves issue #270.

v0.2.0-beta.3

This is pgx v0.2.0-beta.3. It fixes a few issues reported during beta2.

Fixed Issues

• #268: #[pg_extern] functions with lifetimes no longer cause compiler errors
• #262: Add a --no-schema flag to cargo pgx run/test/install which avoids generating the schema again. This can help speed up the development cycle if you haven't made any code changes that would affect the SQL schema

v0.2.0-beta.2

This is pgx v0.2.0-beta.2. As the second beta in the 0.2.0 series, it adds a few small features and a handful of bugfixes.

If upgrading from the 0.1.x series, please see the release notes for beta1 (https://github.com/zombodb/pgx/releases/tag/v0.2.0-beta.1).

New Features

• PostgreSQL v14 support (#245)

Bug Fixes

• Resolve undefined behavior around exported function symbols (#241)

  • As a result there is now pgx::direct_function_call() and pgx::direct_pg_extern_function_call() for dynamically calling internal Postgres functions and functions you declare as #[pg_extern].

• Fix up Darwin linking issues (#244)

• Resolve issues with sql entity graph generation (#236, #260)

Thanks!

Thanks to everyone that contributed testing and issue reports during this beta. Most especially @rustprooflabs!

v0.1.25

This is a follow-up to v0.1.24 that resolves safely issues around trapping Rust panics and Postgres ERRORs across FFI boundaries.

This will be the last release in the 0.1.x series (and this time we mean it!), and the previous v0.1.23/v0.1.24 releases will be yanked from crates.io.

v0.1.24

This is pgx v0.1.24. It is a follow-up to the v0.1.23 release which inadvertently broke shared memory support. This release fixes that.

Also note that this will be the last release in the 0.1.x series, as we are finalizing a v0.2.0 release which brings some breaking changes along with PostgreSQL 14 support.

v0.1.23

This is pgx v0.1.23. This is a soundness/safety release that fixes undefined behavior related to functions declared as #[pg_extern]. Primarily, it resolves issue #241.

v0.2.0-beta.1

Features

• The pgx SQL generation system has been rewritten! It now uses the proc macro system and has several breaking changes. Please refer to the migration guide below. (#165, #197)
• The PostgreSQL uuid type is now supported! (#172)
• cargo pgx test now accepts an optional testname. cargo pgx test specific::path works just like cargo test! (#186)
• pgx-pg-sys now suggests you install rustfmt if you don't have it. (#193)
• cargo pgx schema will now emit informational messages if extension Cargo.toml settings are not what is expected. (#209)
• cargo pgx test now has a --workspace argument matching the equivalent on cargo test. (#169)

Other changes

• fix: Marked several functions as unsafe as they had undefined behavior when passed invalid pointers. (#210, #216, #217, #223, #224, #226)
• Type oids don't need to be looked up in functions that don't use them. (#168)
• Added an aggregate example. (#187)
• Updated many of our dependencies. (#191)
• More documentation has been added to several macros and SQL generation related types. (#192, #158, #219)
• An articles/ directory now exists in the repo and includes links to different articles written about pgx. (#198)
• Document our MSRV (#157)
• Fixed an accidental circular dependency in 0.2.0-beta.0 (unpublished).

Migration Guide

1. Update your cargo-pgx: cargo install --force cargo-pgx --version 0.2.0-beta.0

2. In your Cargo.toml, set crate-type to include "rlib" and profile.dev.lto to be "thin":

   [lib]
   crate-type = ["cdylib", "rlib"]
   
   [profile.dev]
   lto = "thin"

3. Tell cargo-pgx to force update your .cargo/ and src/bin files it needs: cargo pgx schema -f

4. Remove any sql/*.generated.sql files, as well as the load-order.txt.

5. For each sql/*.sql remaining, insert extension_sql_file!("../sql/that_file.sql"); into your src/lib.rs

6. If the files depend on entities which already exist, you might need to set a requires attribute:

   extension_sql_file!("../sql/that_file.sql", requires = [ dogs::parts::Floof, some_fn, ]);

7. For any mod floof { fn boop() { todo!() } } style blocks you were using to infer schema name (making that function floof.boop), decorate the schema with #[pg_schema]:

   #[pg_schema]
   mod floof {
       fn boop() {
           todo!()
       }
   }

8. For any functions have a custom sql block for (like below), update that to use pgxsql now:

   /// ```sql <-- Change this to `pgxsql`
   /// CREATE OR REPLACE FUNCTION  ....
   /// ```
   #[pg_extern]
   fn dot_dot_dot() { todo!() }

9. Run cargo pgx schema again!

If you have any trouble, try running cargo pgx schema -v and investigating the output. We made sure to update the cargo doc output of pgx with updated usage for the various macros and derives, they might have some advice, too.

You can ask us questions via issues here or Discord if you get stuck.

Thanks!

Thanks to @JLockerman (from @timescale) & @kpumuk for contributions! Also thanks to our early testers @rustprooflabs and @comdiv.
