Did so, and look what popped up on wrasse [1]:

! nm -A -g -u libpq.so.5.15 2>/dev/null | grep -v __cxa_atexit | grep exit
libpq.so.5.15: [765] | 232544| 248|FUNC |GLOB |3 |14 |PQexitPipelineMode

This makes no sense, because (a) wrasse was happy with the previous
version, and (b) surely the "-u" switch should prevent nm from
printing PQexitPipelineMode. Noah, did you change anything about
wrasse's configuration today?
