Обсуждение: No Interval Conversion Function in 7.2?!!?

Folks,

Please help!  I just upgraded a production database to PostgreSQL 7.2,and discovered that INTERVAL() is no longer a
function. What replacedit?  How can I convert VARCHAR to Interval?

It's still there, but INTERVAL is a reserved word these days.
"INTERVAL"(varcharvalue)
varcharvalue::interval
CAST(varcharvalue AS interval)

should all give the same results.  Only the last of these is actually
standard.

Sigh, that one should be
"interval"(varcharvalue)
