Sorry, I cannot understand what you mean...

My English might be broken. May I explain what I did again?

1. psql has been used pg_get_triggerdef(oid).

2. I added pg_get_triggerdef(oid, pretty = false) at the last commit fest
for pg_dump to support dumping triggeres with WHEN cluase. In that time,
PRETTYFLAG_PAREN and PRETTYFLAG_INDENT are used when pretty = true.

3 psql still uses pg_get_triggerdef(oid [, pretty=false] ).
Also, pg_dump should use (pretty=false) for safer migration.
No programs use pg_get_triggerdef(pretty=true) is for now.

4. psql will be better to use pg_get_triggerdef(oid, true) to display
trigger definitions cleanly, but it also should print them in one line.
For the purpose, the patch changes two things:
- Modify psql to use pg_get_triggerdef(oid, true) when server version >= 8.5.
- Remove PRETTYFLAG_INDENT from pg_get_triggerdef(). It will partially
revert the changes in 2.
