From f08842a0d8198f3faaf2b2457ed77f373ea6d60f Mon Sep 17 00:00:00 2001 From: Claude Date: Tue, 18 Aug 2026 19:25:45 +0000 Subject: [PATCH] Fix govulncheck failure by removing lib/pq from default builds govulncheck fails on seven unpatched lib/pq vulnerabilities (GO-2026-6166 through GO-2026-6171). All of them are reported with 'Fixed in: N/A', so bumping the dependency cannot fix the check. The sqlc binary itself never uses lib/pq; the module only linked it in two places that govulncheck's default (untagged) scan could see: - internal/sqltest/postgres.go registered the lib/pq driver, but its helpers (PostgreSQL, CreatePostgreSQLDatabase) have no callers left, so delete the file and move the id() helper to mysql.go, which still uses it. - examples/ondeck/postgresql generated code imports lib/pq for pq.Array. Its tests are already build-tagged 'examples', so set build_tags: examples for the package in sqlc.json and regenerate, putting the generated files behind the same tag as the tests that exercise them. With no lib/pq import left in the default build, govulncheck reports zero called vulnerabilities; lib/pq remains a module requirement for the examples-tagged tests, which is informational only. Verified with govulncheck ./... (0 findings), go build/vet with and without the examples tag, and the example test suites against live PostgreSQL and MySQL.
