Problems installing Postgresql ODBC driver 32bits on Redhat 6.5

Hello,  please

When the pkg postgresql-odbc-7.0.2-17.i386.rpm was installed, It returned this error:

isql -v rep_teste

[01000][unixODBC][Driver Manager]Can't open lib '/usr/lib/psqlodbc.so' : file not found
[ISQL]ERROR: Could not SQLConnect

When the pkg postgresql-odbc-7.2.5-1.i386.rpm was installed, the lib above was installed, but we got the error:

isql -v rep_teste

[IM002][unixODBC]Missing server name, port, or database name in call to CC_connect.
[ISQL]ERROR: Could not SQLConnect

We guess the /etc/odbc.ini is correct:

[rep_teste]
Description         = PostgreSQL connection to SallyDB
Driver                 = PostgreSQL
Database            = rep_teswte
Servername         = vmhteste
UserName           = teste
Password           = 123456
Port                    = 5432
Protocol              = 9.4
ReadOnly            = No
RowVersioning       = No
ShowSystemTables    = No
ConnSettings        =

We think there are a postgresql-odbc package mistake but we can't find the correct package.

We'll apprecciate any help. Thank !!.
