Odd --- I get the right thing:
$ psql -?
This is psql, the PostgreSQL interactive terminal.
Usage: psql [options] [dbname [username]]
Options: -a Echo all input from script -A Unaligned table output mode (-P format=unaligned)
[etc etc]
Something different about long-option handling on your platform, maybe?
What is your platform, anyway?

It has something to do with certain shell's expansion of ? - for the longest time I'd have to do psql -\? to get it to work. -- Dominic J. Eidson "Baruk Khazad!

It's a shell thing: Vince is running csh (or a derivative thereof) while Tom (and I) are running some sort of Bourne derived shell. Vince, try: psql -\? Which works more universally.

all you guy unix? under some shells, both * and ? are expanded to matched file names in current directory by shell, for example FreeBSD's csh. you should use psql -\? to get help screen, this sucks, "?" shouldn't be used as a help screen argument.

I tend to agree, given csh's unhelpful (ahem) behavior.
At the very least, it seems that "psql -h" ought to produce
the full help message, not just a complaint that the syntax
is wrong.
