PostgreSQL's official Docker images ship barebones, leaving developers to manually compile extensions like pgvector and PostGIS for AI or geospatial features. This tedious process often forces teams to rely on third-party images with fixed extension bundles, creating compatibility and maintenance headaches.

pglayers eliminates the compilation step entirely. The tool publishes each extension as a minimal Docker layer containing only binaries, which developers stack onto official postgres images using COPY --from commands. No compilers, dependencies, or build tools required—just pull and compose.

Two deployment paths are available: pre-built images like pglayers-full with 53 extensions, or custom combinations mixing specific extensions such as pg_cron, PostGIS, and pg_partman. Each layer uses multi-architecture tags supporting both AMD64 and ARM64 platforms automatically.

Currently supports PostgreSQL 17 and 18 stable releases, with 19 in experimental status. Some extensions require shared_preload_libraries configuration in postgresql.conf. Vendor profiles like pglayers-azure approximate cloud services but shouldn't replace actual managed offerings for production workloads.
