Download PostGamma¶

Official binaries are published only after the complete release matrix passes. GitHub Releases is the canonical home for static SDK archives, checksums, and wheel mirrors. PyPI receives the exact same tested wheel bytes.

CURRENT CANDIDATE

0.1.0a1 · alpha¶

The first public binary release is being prepared for Linux x86-64. Until it is published, build from source or use an explicitly shared candidate artifact. Only assets attached to a published release are official release artifacts.

Python¶

Once the release is published, select this alpha explicitly and let pip choose the wheel for the active CPython interpreter:

python -m pip install "postgamma==0.1.0a1"

The initial matrix contains one manylinux_2_17_x86_64 wheel for each of CPython 3.10, 3.11, 3.12, 3.13, and 3.14. No source distribution is published in this release, so installation fails instead of compiling an unverified local kernel when no compatible wheel exists.

To install a wheel downloaded from GitHub Releases:

python -m pip install ./postgamma-0.1.0a1-*.whl

Static C SDK¶

The native release asset is:

postgamma-sdk-0.1.0a1-linux-x86_64.tar.gz

It contains libpostgamma.a, public headers, postgamma.pc, a complete resource pack, a compiled example, and all required license notices. Download the archive and its adjacent checksum from the same release:

sha256sum --check \
  postgamma-sdk-0.1.0a1-linux-x86_64.tar.gz.sha256
tar -xzf postgamma-sdk-0.1.0a1-linux-x86_64.tar.gz

Verify a release¶

Every GitHub Release contains:

Asset	Purpose
`postgamma-*.whl`	Platform-specific CPython distributions
`postgamma-sdk-*.tar.gz`	Static C SDK and matching resource pack
`SHA256SUMS`	Digests for every published payload and the manifest
`release-manifest.json`	Version, PostgreSQL major, platform contract, roles, sizes, and tested digests
`LICENSE`, `NOTICE`, and third-party notices	Redistribution terms and attribution

Verify the complete downloaded set before redistribution:

sha256sum --check SHA256SUMS

Release assembly uses the hashes produced by the wheel and static-SDK test gates. A release is rejected if an asset was rebuilt or changed after those tests.

Supported binary target¶

Component	Initial target
Operating system	Linux
Architecture	x86-64
CPU baseline	x86-64-v1; no AVX requirement
libc	glibc 2.17 or newer
Python	CPython 3.10–3.14
PostgreSQL cluster major	19
C delivery	Static SDK; versioned ABI 1.4

Developer builds made on newer Linux systems may require a newer glibc. Only the official release matrix carries the manylinux_2_17 compatibility claim.

Source builds¶

The repository keeps PostgreSQL and bundled extension sources as submodules. From a complete checkout:

git submodule update --init --recursive
make release-candidate JOBS=8

This produces a tested local wheel, static SDK, documentation site, and release receipt. It does not upload or publish anything.

Read the versioning policy before comparing builds or upgrading a cluster.
