between Postgres and PostgreSQL.

(inadequate anyway) mention of SELECT INTO from the main SELECT ref page.
Point out that SELECT INTO means something else in plpgsql and ecpg.

ecpg reference page still needs formatting.

No big deal; fixed lots of other markup at the same time.
Bigest change: make sure there is no whitespace
 in front of <term> contents.
This will probably help the other output types too.

Split reference pages for CREATE TABLE AS and SELECT INTO to allow psgml
 (the emacs parser) to handle parsing.
