Hi,
I met some problem with get date type value
from a table. I have a Datum which stores this
value as an integer and I want to get its date
value. Is there anyway that I can print it out?

Best Regards,

Re: Get Date value from Datum

What do you want to print? The integer value or the date string like
"29-01-2008". Use the date_out function to convert your value to date.

Maybe inspecting the code of debugtup also helps, see

src/backend/access/common/printtup.c

(http://git.postgresql.org/?p=postgresql.git;a=blob;f=src/backend/access/common/printtup.c#l504)
