CI: Run snowflake regressions against PostgreSQL 19 - #48
Merged
Conversation
Add 19 to the regression matrix. PG 19 has not gone GA, so the only tags on the postgres repo are REL_19_BETA1..BETA3, and the previous tag selection filtered them out (its `REL_[0-9]+_[0-9]+` regex only matches numeric minors), leaving LATEST_TAG empty and `git checkout` failing. Rework the tag-selection step to prefer the newest stable minor and fall back to the newest BETA/RC tag when a major has no stable release yet. sort -V orders BETA1 < BETA2 < BETA3 < RC1, so today PG 19 resolves to REL_19_BETA3 and will pick up BETA4/RC1/REL_19_0 automatically as they are tagged. An unresolvable major now fails loudly instead of silently checking out nothing. Also pass the version through the environment instead of interpolating it into a double-quoted docker exec string, which lets the inner script be single-quoted and drop the backslash escaping.

In @.github/workflows/snowflake_regression_tests.yml:
- Around line 125-133: Ensure the workflow’s use of sort -V in the LATEST_TAG
selection is supported on Alpine by installing GNU coreutils before this step,
or replace both version-sorting pipelines with portable ordering while
preserving stable and pre-release tag precedence.
- Line 17: Update the snowflake regression workflow to declare read-only
contents permissions for actions/checkout, then remove the tokenized clone URL
and GITHUB_TOKEN environment injection from the checkout configuration. Keep
repository checkout functioning through the standard checkout behavior without
exposing a token to PR-controlled code.

pgEdge/snowflake is public, so the clone needs no credential. The token was interpolated by the runner shell straight into the docker exec argument list, which put it on the container's command line in a job that builds PR-controlled code. Clone anonymously instead, drop the now-unused GITHUB_TOKEN from the step environment, and pin the workflow to permissions: contents: read so the token actions/checkout does use cannot write to the repo.
