As part of a research project I would like to change the source code of Postgres. There, I want to do the following: I want to stop the optimizer at some place, issue a query from the optimizer and use the result of the query to continue the optimization process.
Is there a good and clean way how I could do this? I want to submit another query inside the existing connection and optimizer code. Is there some function I could use? I don’t want to do a hardcoded scan of a table, I want to build a query string and use the parser, analyzer, optimizer, and executer to submit the query. Thanks a lot! Robert
