* NOTE: SQL92 says you can't write column aliases unless
* you write a table alias --- but the table alias could
* be spelled the same as the table's real name. This
* logic is therefore all wet: it should go something like
* IF we-need-to-dump-column-aliases OR relname != refname
* THEN print refname;
* IF we-need-to-dump-column-aliases
* THEN print column alias list.
* But currently we can't tell whether we need to dump
* column aliases or not... without that, this clearly
* backwards logic seems the best short-term approach.
* Since we don't really support SQL joins yet, dropping
* the list of column aliases doesn't hurt anything...
* you write a table alias --- so, if there's an alias list,
* make sure we emit a table alias even if it's the same as
* the table's real name.
