Or is that a stupid idea? I just think hacking libpq for something like this is a huge overkill.
I don't think so only plpgsql solution is satisfactory idea. There are some mix plpgsql / plperl ... application - and it isn't possible to remove error context from only one language.
Yeah, not in libpq it isn't. Thing is, PL/PgSQL already is the exception here, since it's the only language which does this error message suppression. So if people did think this suppression was a good idea, only the people using PL/PgSQL were vocal enough to get the behavior changed. I'm not looking to change that.
I can see where it's a lot nicer not to have the context visible for people who only care about the contents of the message, but the way it's done in PL/PgSQL right now is just not good enough. On the other hand, the backwards compatibility breakage of doing this in libpq is quite extensive. The most simple option seems to be to just allow a GUC to change PL/PgSQL's behavior to match what all other PLs are doing.
libpq was changed more time - there is still a open task about a protocol change.
I afraid about some unexpected side effects of your proposal if somebody mix languages - these side effects should not be critical - but on second hand current behave is not critical too - we can wait.
