I'm working on a system where postgres 8.2.1 was built from source on Solaris 10 using gcc. Based on a number of recommendations, we decided to rebuild postgres Sun Studio cc. Without changing platforms, I wouldn't've expected the compiler to make a difference, but we just built 8.2.2 from source using cc, and now we're seeing this type of error in the logs:
ERROR: attribute 3 has wrong type
DETAIL: Table has type character varying, but query expects character varying.
Is changing compilers under postgres on the same platform without a dump/reload a Bad Idea?
More important: Has this risked any catastrophic data corruption? If we just switch to a gcc 8.2.2, will we be fine?
