Pgx_unix - PGX using the standard library's Unix module for IO (synchronous)
README


PGX is a pure-OCaml PostgreSQL client library, supporting Async, LWT, or
synchronous operations.

This is an early release. The API is likely to change significantly before
the 1.0 release.

This library focuses on correctness and safety, with features like:

  • It is nearly impossible to try to execute a prepared statement that hasn't
    been prepared.

  • Trying to run multiple queries at the same time will work properly (although
    there's no performance benefit, since we currently don't send queries in
    parallel).

  • Lots of automated tests.

  • Pgx.Value for parameters and returned data, encouraging people to use
    the built-in converters instead of trying to handle everything as a string.

  • Async and LWT support are built in, no need to write your own IO module.

We also provide a relatively high-level interface, like Pgx_async.execute_pipe,
which prepares a statement, executes it with the given parameters, returns an
Async.Pipe.Reader.t (so you can stream results), and unprepares the statement
when the query is finished.

Significant portions of the code come from PG'Ocaml.
