BUG #18581: psql symbol append_history not found when quitting

The following bug has been logged on the website:

Bug reference: 18581
Logged by: Rainer Brandt
Email address: rjhb(at)bb-c(dot)de
PostgreSQL version: 15.8
Operating system: Solaris 11.4
Description:

When leaving a psql session via \q in 15.8 (which I built today under Oracle
Solaris 11.4), I get:
ld.so.1: psql: fatal: relocation error: file
/opt/postgres/15-pgdg/bin/64/psql: symbol append_history: referenced symbol
not found
Killed

Then with nm:
nm /opt/postgres/15-pgdg/bin/64/psql | grep append_history
[1744] | 4296745248| 0|FUNC |GLOB |0 |UNDEF
|append_history
[1511] | 4295420712| 112|FUNC |GLOB |0 |14
|pg_append_history

Previously, I used 15.6, which only uses pg_append_history and doesn't use
append_history.

I also see:
grep -n append_history postgresql-15.8/src/bin/psql/*
postgresql-15.8/src/bin/psql/input.c:114:pg_append_history(const char *s,
PQExpBuffer history_buf)
postgresql-15.8/src/bin/psql/input.c:133: * pg_append_history before we'll
do anything.
postgresql-15.8/src/bin/psql/input.c:453: /*
append_history fails if file doesn't already exist :-( */
postgresql-15.8/src/bin/psql/input.c:462: errnum =
append_history(nlines, fname);
[...]

Isn't the a "pg_" missing on line 462?

Thank you.
