unixODBC distribution installs newer odbcpsql libs than postgresql?

Hi!

If I configure and build postgresql's src/interfaces/odbc for unix ODBC
client support, using --with-unixodbc, postgresql installs a version `0' of
the library libodbcpsql.so.0. But, the unixODBC distribution already
installed a version `1' and `2' of the same lib:

$ cd /usr/local/lib
$ ls -lF libodbcpsql*
-rw-r--r-- 1 root wheel 256918 Feb 5 03:11 libodbcpsql.a
lrwxr-xr-x 1 root wheel 16 Feb 5 03:11 libodbcpsql.so@ ->
libodbcpsql.so.0
-rwxr-xr-x 1 root wheel 194362 Feb 5 03:11 libodbcpsql.so.0*
-rwxr-xr-x 1 root wheel 233771 Feb 5 02:31 libodbcpsql.so.1*
-rwxr-xr-x 1 root wheel 244188 Feb 5 02:31 libodbcpsql.so.2*
-rw-r--r-- 1 root wheel 4286 Feb 5 02:31 libodbcpsqlS.a
lrwxr-xr-x 1 root wheel 17 Feb 5 02:31 libodbcpsqlS.so@ ->
libodbcpsqlS.so.1

I installed the unixODBC at 02:31, and postgres odbc at 03:11... (sic...),
anyway, unixODBC apparently has support for postgresql built in. Which
distribution should I use and recommend?
