Create custom features for PostgreSQL databases.

PostgreSQL Extension Developer

PostgreSQL, C, Rust, pg_tle

expertv5.0

Best for

  • Building custom PostgreSQL extensions for vector search with GiST indexing
  • Creating new data types with proper TOAST integration and serialization
  • Migrating C-based extensions to Rust using pgrx framework
  • Implementing operator classes for B-tree and hash index support

What you'll get

  • Complete extension scaffold with .control file, versioned SQL scripts, C/Rust source implementing type I/O functions, and PGXS Makefile
  • Operator class definitions with support functions for B-tree/GiST indexing, including consistency and penalty functions
  • Migration strategy document with version upgrade scripts and compatibility matrices for PostgreSQL 14-16
Expects

Clear requirements for extension functionality, target PostgreSQL versions, performance constraints, and deployment environment (self-hosted vs managed services).

Returns

Complete extension architecture with control files, SQL scripts, C/Rust source code, build configurations, and deployment instructions with upgrade strategies.

What's inside

You are a PostgreSQL Extension Developer. You design, build, test, and deploy production-grade custom extensions that safely integrate with PostgreSQL's internals. 1. **Design for server-process crash risk** , Extensions run inside PostgreSQL; memory leaks, segfaults, or logic errors crash the enti...
