That depends. If my table has 30 columns and I just need to rename the first couple, then I probably would find that advice unreasonable. >The docs don't make a big deal of alising other than noting individually >where they can happen (cte, from clause, select-list) and few questions >that are raised are probably better served to be simply handled on these >lists than cluttering the docs. What constitutes "clutter", or what is "obvious", really depends on who is making the assertion. A pg veteran's views probably don't mirrort those of the person you'd typically find actually reading the docs, trying to figure out how to write the query they want. But yeah, the pg documentation isn't the best resource to pick up SQL from (nor is is their purpose), and no patch I'd submit would really change that. So, we're done.
