Did you install the header files ?
If you are installing a binary that is compiled to use the library,
the library is enough. If you are compiling from scratch, you need the
.h files as well.
On Debian potato the command is:

Check that you have the readline header files installed (and if configure
finds them; readline.h, history.h or similar). Look for RPMs
readline-devel or some such.

This opinion has less to do with Postgres and more to do will a general
philosophy but we always use a 4 byte integer column as the primary key for
almost every table. None of the following reasons means it has to be that

Friends,
Yesterday I upgraded from 7.1.3 on RedHat 6.2 to 7.2.1 on RedHat 7.2, and
now I'm having problems with ODBC connections from access on windows. The
problem I'm having is that I am unable to change or delete data; it says

If you're talking about multiple databases served by a single
postmaster, I don't believe it's much of an issue.
Hi Jodi,
Its to stop the triggers firing when you restore the new database from
the dumped file.
Imagine that the triggers have already done their work on other tables
when the data was first inserted or
later changed.

Ciao Gianmarco;
You can upgrade your pg installation by using the rpm version.
download the rpm version, the latest at the moment could be the 7.2, and
try to upgrade your intstallation using the RPM command.
