Allow the pg layer to work for simple selects with the postgres_fdw ------------------------------------------------------------------- Key: TEIID-5498 URL: https://issues.jboss.org/browse/TEIID-5498 Project: Teiid Issue Type: Sub-task Components: ODBC Reporter: Steven Hawkins Assignee: Steven Hawkins Priority: Major Fix For: 11.2 Another avenue for materialization support outlined in TEIID-4251 is to rely upon pg materialization, which would be easiest to setup through their foreign data wrapper. However it expects some additional support for: start transaction syntax abort transaction automatic cleanup of portals/cursors at the end of a transaction prepared cursors Additionally this will have the same performance issue that we have with declare/fetch initially - that is a cursor requires a transaction, and our current strategy requires pre-buffering the results under a transaction. However since this would only be used for load/refresh that performance hit may be negligible - if now we'd need similar logic to effectively ignore the transaction wrapping.
