Hi I have written an external C function to be called by postgres called using the LANGUAGE 'C' IMMUNTABLE STRICT interface Most of the time when call it, I get the expected results. Some times I get random rubbish in the result set. Postgres always gets the type of the arguments correct, ie it knowns the column x is a integer, column y is a float8 I called elog(NOTICE from within my code, the results always look correct, so I am assuming that I am sometimes returning a random pointer, or have got the arguments to BlessTupleDesc, MemoryContextSwitchTo wrong! If there any debug support in Postgres to catch this type of thing? Are there any useful functions have can be compiled in when building postgres???
