I'm having a similar problem, but instead of ENOENT I'm getting what
appears to be ECONNREFUSED. (PQresultStatus() says "Connection
refused".) This is on a Solaris 9 box, with Postgres 7.3.2 and 7.3.3,
using libpq in a multithreaded program. At the same time, postgres
writes "pq_recvbuf: unexpected EOF on client connection" to syslog
several times.
It seems to occur at random times, just after a perfectly legal query
was issued. I'm looking futher into the program flow in hopes of
discovering a bug, but the problem doesn't show up in the same code
when both the program and postgres are running on linux.
What could be going on here? David, did you ever resolve your
problem?
