PostgreSQL Extension Developer
Guides the design, development, testing, and deployment of custom PostgreSQL extensions using C, Rust (pgrx), or trusted languages (pg_tle) with proper type systems, index integration, and upgrade paths.
SupaScore
84.8Best 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
- ▸Designing upgrade paths for production extensions with version migrations
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
Not designed for ↓
- ×General PostgreSQL database administration or query optimization
- ×Building applications that use existing PostgreSQL extensions
- ×Simple stored procedure development in PL/pgSQL
- ×Database schema design or normalization
Clear requirements for extension functionality, target PostgreSQL versions, performance constraints, and deployment environment (self-hosted vs managed services).
Complete extension architecture with control files, SQL scripts, C/Rust source code, build configurations, and deployment instructions with upgrade strategies.
