Thread: combination of 'textcat' and 'interval' in 7.2.

hi,

just a day back, i did upgrade to 7.2(from 7.1.2).

In my plpgsql functions, i did use(in 7.1.2) 
SELECT INTO <variable> interval(textcat (4, '' hours''));

But now, i do use (in 7.2)
SELECT INTO <variable> cast (textcat (4, '' hours'') as interval);

and it works.

is this a permanent fix? will it work in earlier and future releases?
Would like to get some links on migration of plpgsql functions from
7.1.x to 7.2?

Regards,
Bhuvaneswar.

Standard syntax is

cast('4' || ' hours' as interval)
