Build PostgreSQL extensions with OCaml

pgo

EXPERIMENTAL AND INCOMPLETE

Build PostgreSQL extensions in OCaml.

Overview

• The project uses ctypes with C stubs generation to interface with PostgreSQL/C API (both to use PostgreSQL/C API and to expose OCaml functions to PostgreSQL).

• Library pgo.api provide bindings (type definitions and functions bindings) to PostgreSQL/C API.

• Library pgo.fdw sketches a harness for implementing FDW with OCaml.

• Library example/fdw implements an example FDW which exposes a single table.

Development

1. Make sure you have opam and PostgreSQL installed.

2. Initialize opam switch:

   make init
   

3. Build the project:

   make build
   

4. Initialize the test database:

   make test-db
   

5. Run psql shell within the test database with the example extension loaded:

   make psql
