How to see the CREATE VIEW code for a view in PostgreSQL?

Kept having to return here to look up pg_get_viewdef (how to remember that!!), so searched for a more memorable command... and got it:

\d+ viewname

You can see similar sorts of commands by typing \? at the pgsql command line.

Bonus tip: The emacs command sql-postgres makes pgsql a lot more pleasant (edit, copy, paste, command history).

select pg_get_viewdef('viewname', true)

A list of all those functions is available in the manual:
