Hi,
I had similar errors here and there after moving to 8.3.3 from 8.2.x., no more
automatic casts.
"ERROR: operator does not exist: character varying = integer at character 286
HINT: No operator matches the given name and argument type(s). You might need
to add explicit type casts."
Quick fix to sql statements eg.
... WHERE CAST (your_char AS INTEGER) = integer ...
... WHERE CAST (your_char AS INTEGER) IN (1,2,3,...)
BR,
