Add OID data type in Postgres-Pandas Type Mapping

[Ami-Mamidala]

Hello, According to the SFU-DB ConnectorX Postgres page (https://sfu-db.github.io/connector-x/databases/postgres.html), 'OID' Postgres Type is not specified in the list. Could it be converted into the Pandas type 'object' so that ConnectorX does not show a 'PanicException' when converting output from a query into a Pandas DataFrame?
