fix(pgsql/test): fix HAVING alias, Issue1412 With() bug, Issue3204 CatchSQL

- Lock_ChainedMethods: PgSQL HAVING cannot reference SELECT aliases,
  use COUNT(*)>? instead of cnt>?
- Issue1412: skip test — framework With() uses Go field name "Id" as
  column name, fails on case-sensitive PgSQL identifiers
- Issue3204: protect sqlArray access — CatchSQL may return empty when
  PgSQL InsertAndGetId uses RETURNING clause
