Author Solaris - psql returns 0 instead of 1 for file not found.

Hi all,

I've found the when psql is used with the -f flag and the specified file
doesn't exist the rc value is 0.

$ uname -a
SunOS bld 5.8 Generic_108528-29 sun4u sparc SUNW,Sun-Fire-V440

$ psql -V
psql (PostgreSQL) 8.0.2

$ ls foo
foo: No such file or directory

$ psql -f foo
foo: No such file or directory

$ echo $?
0

However, in the man page for psql it says:

EXIT STATUS
psql returns 0 to the shell if it finished normally, 1 if a
fatal error of its own (out of memory, file not found)
occurs, ...

I'm assuming this is the same with other platforms, but I only use
PostgreSQL on Solaris.

Has this been fix in 8.0.3?

Cheers,
Andrew

I have applied the following patch to 8.1beta and 8.0.X to return the
proper failure value for a psql -f filename open failure.

The bug was that process_file() was returning false for failure, while
the call site expected MainLoop() return values, meaning false/0 was
success.

Redirecting to -bugs since I've confirmed this behavior on Slackware Linux 10
with psql version 8.1beta1 and there does seem to be something wrong with the
above situation (perhaps the man page needs to be reworded?)
