I was wondering the same thing. I read the html manual, O'Reilly's
Practical PostgreSQL, Sam's PostgreSQL Developer's Handbook and have
browsed http://techdocs.postgresql.org. I also lurk on this list and
ocasionally ask and answer questions. Where in all that information am I
supposed to pick up that 'SELECT max(foo) FROM quux' should be written as
'SELECT foo FROM quux ORDER BY foo LIMIT 1'. That's really unintuitive and
if this info isn't in the docs I've read so far, I'm not sure where it is.
Am I supposed to read the source for comments as well? So mostly I just
want to know where these suggested work arounds are documented. Is there a
particular set of keywords that work for searching the hacker's list? I'm
at a loss as to where to get this (obviously) valuable info.
Pointers would be appreciated,
