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

Question

Is there an easy way to see the code used to create a view using the PostgreSQL command-line client   Something like the SHOW CREATE VIEW from MySQL

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

These is a little thing to point out  Using the function pg get viewdef or pg views or information schema views you will always get a rewrited version of your original DDL  The rewited version may or not be the same as your originl DDL script  If the Rule Manager rewrite your view definition your original DLL will be lost and you will able to read the only the rewrited version of your view definition  Not all views are rewrited but if you use sub-select or joins probably your views will be rewrited
