* feat: detect psycopg[binary] and skip apt packages
When using psycopg2-binary or psycopg[binary], the PostgreSQL client
libraries (libpq-dev, libpq5) are not needed because these variants
ship with pre-compiled binaries. This change:
- Adds usesBinaryPsycopg() to detect binary variants
- Updates usesPostgres() to return false when binary variants are used
- Skips libpq-dev (build) and libpq5 (runtime) apt package installation
- Adds comprehensive unit tests for binary psycopg detection
This reduces image size and build time for projects using binary variants.
* test: add psycopg[binary] integration test
Adds a dedicated test example for psycopg[binary] to verify that the
bracket syntax for optional dependencies is correctly detected. This
ensures the binary detection works for both psycopg2-binary and
psycopg[binary] variants.
Test coverage now includes:
- psycopg2-binary (existing python-system-deps example)
- psycopg[binary] (new python-psycopg-binary example)
- psycopg non-binary (existing python-latest-psycopg example)
- psycopg2 non-binary (existing python-django example)
* test: snapshot update
* test: add binary pyscogp test
* test: ensure libpq is installed for pyscog operation
* build: add helper for running the current dir tests
* test: check to make sure the libpg library is not installed when a binary postgres connection is requested
* test: update snapshot
