PgDog plugins

PgDog plugin system is based around shared libraries loaded at runtime. The plugins currently can only be written in Rust. This is because PgDog passes Rust-specific data types to plugin functions, and those cannot be easily made C ABI-compatible.

This crate implements the bridge between PgDog and plugins, making sure data types can be safely passed through the FFI.

Automatic checks include:

• Rust compiler version check
• pg_query version check

This crate should be linked at compile time against your plugins.

Writing plugins

See documentation for examples. Example plugins are available in GitHub as well.
