chore: bump github.com/lib/pq from 1.11.2 to 1.12.1

[dependabot]

Bumps github.com/lib/pq from 1.11.2 to 1.12.1.

Release notes

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

v1.12.1

• Look for pgpass file in ~/.pgpass instead of ~/.postgresql/pgpass (#1300).

• Don't clear password if directly set on pq.Config (#1302).

#1300: lib/pq#1300 #1302: lib/pq#1302

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).

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
