The following bug has been logged online:
Bug reference: 1467

PostgreSQL version: 8.0.1
Operating system: All
Description: fe_connect doesn't handle EINTR right
Details:
The file pgsql/src/interfaces/libpq/fe-connect.c contains the code fragment
retry_connect:
if (connect(conn->sock, addr_cur->ai_addr,
addr_cur->ai_addrlen) < 0)
{
if (SOCK_ERRNO == EINTR)
/* Interrupted system call - just try again */
goto retry_connect;
}
This is not in accordance with a strict legalistic reading of the POSIX
spec, according to which connect is not restartable so that you have to use
select or poll after connect returned with EINTR.
See
http://www.eleves.ens.fr:8080/home/madore/computers/connect-intr.html
for the ugly details, your code should work on Linux, but not on Solaris or
(Free|Open)BSD.
