Pull request overview

Updates example manifests and E2E image/version inputs to use the percona-distribution-postgresql-with-postgis image (instead of operator-built PostGIS variants), aligning PostGIS usage with the distribution image approach.

Changes:

• Switch PostGIS image references in sample CRs and upgrade manifest to percona-distribution-postgresql-with-postgis.
• Update e2e-tests/release_versions to use distribution PostGIS images for PG 17/18.

1. Problem: IMAGE_POSTGIS17 uses :17.7 while the corresponding PostgreSQL image uses :17.7-2 (and PG18 PostGIS matches 18.1-3), so this looks like an inconsistent/possibly incorrect tag.
2. Why it matters: If :17.7 isn’t a published tag, E2E runs that select the PostGIS 17 image will fail when pulling images.
3. Fix: Align the PostGIS 17 tag format with the repo’s versioning pattern (likely 17.7-2 to match IMAGE_POSTGRESQL17), or confirm/update to the exact existing tag in the registry.

Suggested change

	IMAGE_POSTGIS17=percona/percona-distribution-postgresql-with-postgis:17.7
	IMAGE_POSTGIS17=percona/percona-distribution-postgresql-with-postgis:17.7-2

1. Problem: There are two spaces after image: (image: docker.io/...).
2. Why it matters: While valid YAML, inconsistent whitespace in testdata makes diffs/noise harder to read and can be problematic if any tooling does raw text comparisons.
3. Fix: Use a single space after the colon (image: docker.io/...) for consistency with the rest of the YAML examples.
