Further, little libpq question:
When using INTERVAL types, can I rely on PQfmod(), PQfsize() to determine
the exact definition of the INTERVAL precision?
=> what YEAR/MONTH/DAY/HOUR/MINUTE/SECOND fields where used to create the column.
I get different values for the type modifier, but how to interpret this?
Can someone point me to the documentation or source code where I can find
more details about this?
I found this:
http://www.postgresql.org/docs/8.4/static/libpq-exec.html#LIBPQ-EXEC-SELECT-INFO
But there are not much details in PQfmod() description...
Thanks!
