Well, it will fail unless the user already had /usr/local/pgsql/, but I hear what you're saying. Though I bet almost anyone following this will be able to figure it out but there is little to no value in not being correct. -- Daniel Gustafsson https://vmware.com/

I think that at the time that was written, mkdir didn't universally have a "-p" option. But POSIX has required that for a very long time, so it's probably safe to assume it now. A larger issue is that blind "mkdir -p" may not produce the ownerships and permissions you want for the parent directories. That's not a topic to get into in a one-line summary, though. regards, tom lane

(the fact that IRIX seems to have been one of very few to have a long option '--parents' was an interesting archeological tidbit learned.) > A larger issue is that blind "mkdir -p" may not produce the ownerships > and permissions you want for the parent directories.

I'll to make the mkdir -p change happen later today unless someone feels strongly about leaving it out. -- Daniel Gustafsson https://vmware.com/
