Description:
------------
PDO/pgsql function get_column_meta() return column type id.
But also it return "native_type".
To get "native_type" it make a sql-request: "SELECT TYPNAME FROM PG_TYPE WHERE OID=%d" for each column.

But for our project numeric value of "column type id" is enough.
Requesting "native_type" just slowing down system performance.

So, this is workaround: 
Add new statement option "PGSQL_ATTR_DISABLE_RESOLV_NATIVE_TYPE_ON_META", which prevents resolving "native_type".
