Merge lib/pq upstream (139 commits)

[acoshift]

Summary

Merges 139 commits from lib/pq upstream (upstream/master) into this fork, bringing in the context-support refactor, NamedValueChecker, internal/pgpass extraction, modern Docker-based CI, pqerror package, Config-based options, multi-host/load-balancing, require_auth, SNI/SSL improvements, and many test refactors.

Conflict resolutions

All fork customizations were either already incorporated upstream or made obsolete by upstream's refactors — upstream's version won every content conflict:

• conn.go / conn_test.go — fork's pgpass fix (Fix handlePgpass #1120/ce86388) and NamedValueChecker support (ensure we pass the user and password #2/cbd59e2, Add support for NamedValueChecker interface #1125/402d43b) are now native upstream. pgpass handling moved to internal/pgpass/pgpass.go; CheckNamedValue is at conn.go:863.
• go.mod — bumped from go 1.20 to upstream's go 1.23.
• .github/workflows/test.yml — replaced fork's inline-cert legacy setup with upstream's docker compose + testdata/ CI matrix (PG 14–18, Go 1.23/1.26, pgbouncer, CockroachDB).
• array_test.go / encode_test.go / ssl.go / ssl_test.go — accepted upstream's table-driven rewrites and Config-based API.
• Deleted by upstream:
  • .github/workflows/codeql-analysis.yml (superseded by staticcheck.yml)
  • conn_go18.go (refactored away by the context-support overhaul)
• Manually deleted post-merge (duplicates git couldn't flag because they didn't exist at the merge base):
  • conn_go19.go — CheckNamedValue now lives in conn.go
  • conn_go19_test.go — TestArrayArg is now TestArrayParameter in array_test.go

NullTime

Upstream kept NullTime as a deprecated alias (type NullTime = sql.NullTime). Fork PR #3 removed it entirely; that decision is preserved via a follow-up commit (c910a05) that drops the alias from deprecated.go.

Verification

• go build ./... — clean
• go vet ./... — clean
• go test -run=DontRunAnyTests ./... — all test packages compile (integration tests require a running Postgres)
• auth/kerberos submodule — builds clean

Test plan

• CI passes against PG 14–18 + pgbouncer + CockroachDB
• Spot-check any internal consumer that imported pq.NullTime (now removed)
• Spot-check consumers that relied on Query/Exec (non-Context) on conn — upstream removed these from the public surface

Sorry, wrong repository — meant to target the moonrhythm/pq fork.
