"SELECT column alias, ...": this is a known issue. AFAIK it is not easy
to solve.
"Unquoted object names fold to lower case": this is intentional, both
because the developers prefer this behavior and because it is consistent
with the behavior of prior PostgreSQL versions.
"Implicit FROM item and unintended cross joins": fixed in 8.1, as the
gotcha notes.
"COUNT(*) very slow": this is a known issue -- see the -hackers archives
for many prior discussions. MVCC makes this hard to solve effectively
(whether applications should actually be using COUNT(*) on large tables
with no WHERE clause is another matter...)
