gdb and print debug_query_string?
I don't dispute that this would be nice to have. But I don't think that
it's sane to compromise the postmaster's reliability in order to print
information of doubtful accuracy.
If you want to do something that doesn't violate the system's basic
design goals, think about setting up a SIGSEGV handler that tries to
print debug_query_string via elog before crashing. It might well crash
too, but it won't be risking taking out more of the database with it.
