DB caching on by default?

Hello I tried searching through FAQ's and such, but did not find an answer. Propably sloppy of me. However, I have I problem utilising PEAR DB functions. When I do SELECT that fails due to a fact that a table is missing, then call a function createTable() that does the job fine, and which then calls the select function again, and that is when I receive the same result: table missing error, even though it is there. I am using PostgreSQL under Linux. It worked fine using native PostgreSQL/PHP funcs, so I though there might be some caching turned on by default using PEAR interface. The similar problem appears with INSERT and it buzzles me pretty much. Any quick pointers how to sort out the problem? Cheers, --Jyry :-( C:-/ C========8-O C8-/ C:-(
