Hi,
I'm doing a hacking project which hacks the gram.y file and some other
so that postgres can execute some query plan language to run a
particular plan. I did some modifications and try run it. It compiled
and installed successfully. But when I was trying to run a MergeJoin
operation with keyword MERGEJOIN, it says "ERROR: syntax error at or
near 'MERGEJOIN'". It seems postgres didn't recognize this keyword. Is
it caused by any error inside gram.y? Or how can I trace this error?
Without seeing your grammar changes and the statement you're trying to
execute it's pretty much impossible to tell.
Yeah. One more guess is that you didn't include the keyword in the
keyword list at the end of gram.y. There's script to check various
keyword-related things at src/tools/check_keywords.pl
