PostgreSqlSchemaManager::listTableColumns() fails if there are columns defined by domains in multiple schemas

      We use Postgresql Domains to ensure consistent column definitions across multiple tables. We also have multiple schemas in a database. Therefore we can have two domains defined in the same database with the same name, but in different schemas.

      In this situation, PostgreSqlSchemaManager::listTableColumns() fails when called for a table with a column defined by one of those domains. This means that PostgreSqlSchemaManager::createSchema() also fails for a schema containing such a table.

      SQLSTATE[21000]: Cardinality violation: 7 ERROR: more than one row returned by a subquery used as an expression

      This happens because of an error in the query definition in PostgreSqlPlatform::getListTableColumnsSQL(). The domain_complete_type column in the query is defined by matching the name only, without reference to the schema:

      (SELECT format_type(t2.typbasetype, t2.typtypmod) FROM   
        pg_catalog.pg_type t2                                                        
                             WHERE t2.typtype = 'd' AND t2.typname = format_type(a.atttypid, a.atttypmod)) AS domain_complete_type,                             

      The error can be corrected by making sure that the correct domain is matched by using the OID instead of the name to match:

      (SELECT format_type(t2.typbasetype, t2.typtypmod) FROM   
        pg_catalog.pg_type t2                                                        
                             WHERE t2.typtype = 'd' AND t2.oid = a.atttypid) AS domain_complete_type

      I can create a GitHub PR if it helps.
