build(deps): Bump pgrx-tests from 0.16.1 to 0.18.0

[dependabot]

Bumps pgrx-tests from 0.16.1 to 0.18.0.

Release notes

Sourced from pgrx-tests's releases.

v0.18.0

pgrx v0.18.0

Welcome to pgrx v0.18.0! We cut the build in half.

Schema generation no longer needs a second compilation pass. Your extension compiles once, cargo-pgrx reads SQL metadata straight out of the shared library, and that's it. No more pgrx_embed binary. No more [[bin]] target. No more waiting to compile everything twice.

v0.18.0 also ships in-process benchmarking, a stack of improvements that make pgrx much friendlier to AI coding agents, Rust backtraces for Postgres errors, lazy log allocation, and a handful of quality-of-life fixes that add up to a noticeably better development experience.

Install with:

$ cargo install cargo-pgrx --version 0.18.0 --locked

And make sure to update your crate dependencies to pgrx = "=0.18.0"

One Compilation Pass

#2264 by @​eeeebbbbrrrr

This is the big one.

cargo pgrx schema used to compile your extension, then compile and run a separate pgrx_embed helper binary to extract SQL metadata.

Now it compiles your extension once. The SQL entity metadata is embedded directly into the shared library during the normal build, and cargo-pgrx reads it back out of the .pgrx linker section afterward.

What that means in practice:

• Faster builds. The second compilation pass is gone. If your extension actually takes 45 seconds to build, you were spending ~90 seconds on every cargo pgrx test or cargo pgrx schema. Not anymore.
• Simpler boilerplate. New extensions are just cdylib crates. No src/bin/pgrx_embed.rs. No [[bin]] target. No crate-type = ["lib", "cdylib"]. Just crate-type = ["cdylib"] and your extension code.
• Stricter type resolution. The SQL entity graph now resolves types by TYPE_IDENT (a qualified Rust-side identity using module_path!()) instead of the old loosely-inferred SCHEMA_KEY. Two types with the same name in different modules no longer collide. Types that claim to be extension-owned must actually resolve to a producer in the graph, or schema generation fails. No more silent guessing.

Additionally, the pgrx repo itself is now a proper Cargo workspace with cargo-pgrx, all the core crates, examples, and a dedicated pgrx-unit-tests extension crate. CI exercises the in-tree cargo-pgrx when running tests.

See the v18.0 Migration Guide for the full details and worked examples.
