pointed out, it would need a 2nd pass after the whole query is processed to correctly check that an unknown Param is coerced to the same target type everywhere. Adding the 2nd pass would add a lot more code, which doesn't seem worth the risk given that there isn't much of a use case for passing unknown Params in the first place. The code would work without that check, but it might be confusing and the behavior would be different from the varparams case. Instead, just coerce all unknown params in a PL/pgSQL USING clause to text. That's simple, and is usually what users expect. Revert the patch in CVS HEAD and master, and backpatch the new solution to 8.4. Unlike the previous solution, this applies easily to 8.4 too. |
