Don't use abort(3) in libpq's fe-print.c. Causing a core dump on out-of-memory seems pretty unfriendly, and surely is far outside the expected behavior of a general-purpose library. Just print an error message (as we did already) and return. These functions unfortunately don't have an error return convention, but code using them is probably just looking for a quick-n-dirty print method and wouldn't bother to check anyway.
Although these functions are semi-deprecated, it still seems appropriate to back-patch this. In passing, also back-patch b90e6cef1, just to reduce cosmetic differences between the branches.
