Nice idea.

Marko, just hack ruleutils some thing like this:

diff --git a/src/backend/utils/adt/ruleutils.c
b/src/backend/utils/adt/ruleutils.c
index 266cec5..a46f588 100644
--- a/src/backend/utils/adt/ruleutils.c
+++ b/src/backend/utils/adt/ruleutils.c
@@ -511,8 +511,9 @@ pg_get_viewdef(PG_FUNCTION_ARGS)
{
/* By OID */
Oid viewoid = PG_GETARG_OID(0);
+ int prettyFlags = PRETTYFLAG_INDENT;

- PG_RETURN_TEXT_P(string_to_text(pg_get_viewdef_worker(viewoid, 0, -1)));
+ PG_RETURN_TEXT_P(string_to_text(pg_get_viewdef_worker(viewoid,
prettyFlags, WRAP_COLUMN_DEFAULT)));
}

Thanks
