chore(deps): bump github.com/lib/pq from 1.11.2 to 1.12.0

[dependabot]

Bumps github.com/lib/pq from 1.11.2 to 1.12.0.

Release notes

Sourced from github.com/lib/pq's releases.

v1.12.0

• The next release may change the default sslmode from require to prefer. See #1271 for details.

• CopyIn() and CopyInToSchema() have been marked as deprecated. These are simple query builders and not needed for COPY [..] FROM STDIN support (which is not deprecated). (#1279)

  // Old
  tx.Prepare(CopyIn("temp", "num", "text", "blob", "nothing"))
  // Replacement
  tx.Prepare(copy temp (num, text, blob, nothing) from stdin)
  

Features

• Support protocol 3.2, and the min_protocol_version and max_protocol_version DSN parameters (#1258).

• Support sslmode=prefer and sslmode=allow (#1270).

• Support ssl_min_protocol_version and ssl_max_protocol_version (#1277).

• Support connection service file to load connection details (#1285).

• Support sslrootcert=system and use ~/.postgresql/root.crt as the default value of sslrootcert (#1280, #1281).

• Add a new pqerror package with PostgreSQL error codes (#1275).

  For example, to test if an error is a UNIQUE constraint violation:

  if pqErr, ok := errors.AsType[*pq.Error](https://github.com/lib/pq/blob/HEAD/err); ok && pqErr.Code == pqerror.UniqueViolation {
      log.Fatalf("email %q already exsts", email)
  }
  

  To make this a bit more convenient, it also adds a pq.As() function:

  pqErr := pq.As(err, pqerror.UniqueViolation)
  if pqErr != nil {
      log.Fatalf("email %q already exsts", email)
  }
  

Fixes

• Fix SSL key permission check to allow modes stricter than 0600/0640 (#1265).

• Fix Hstore to work with binary parameters (#1278).

• Clearer error when starting a new query while pq is still processing another query (#1272).

• Send intermediate CAs with client certificates, so they can be signed by an intermediate CA (#1267).

• Use time.UTC for UTC aliases such as Etc/UTC (#1283).

... (truncated)
