2 Recommended UnixODBC settings for PostgreSQL

Installation

  • ** Red Hat Enterprise Linux/CentOS**:
# yum install postgresql-odbc
  • Debian/Ubuntu:

Please refer to PostgreSQL documentation to download necessary database driver for the corresponding platform.

For some additional information please refer to: installing unixODBC.

Configuration

ODBC configuration is done by editing the odbcinst.ini and odbc.ini files. These configuration files can be found in /etc folder. The file odbcinst.ini may be missing and in this case it is necessary to create it manually.

Please consider the following examples:

odbcinst.ini

[postgresql]
       Description = General ODBC for PostgreSQL
       Driver      = /usr/lib64/libodbcpsql.so
       Setup       = /usr/lib64/libodbcpsqlS.so
       FileUsage   = 1
       # Since 1.6 if the driver manager was built with thread support you may add another entry to each driver entry.
       # This entry alters the default thread serialization level.
       Threading   = 2

odbc.ini

[TEST_PSQL]
       Description = PostgreSQL database 1
       Driver  = postgresql
       #CommLog = /tmp/sql.log
       Username = zbx_test
       Password = zabbix
       # Name of Server. IP or DNS
       Servername = 127.0.0.1
       # Database name
       Database = zabbix
       # Postmaster listening port
       Port = 5432
       # Database is read only
       # Whether the datasource will allow updates.
       ReadOnly = No
       # PostgreSQL backend protocol
       # Note that when using SSL connections this setting is ignored.
       # 7.4+: Use the 7.4(V3) protocol. This is only compatible with 7.4 and higher backends.
       Protocol = 7.4+
       # Includes the OID in SQLColumns
       ShowOidColumn = No
       # Fakes a unique index on OID
       FakeOidIndex  = No
       # Row Versioning
       # Allows applications to detect whether data has been modified by other users
       # while you are attempting to update a row.
       # It also speeds the update process since every single column does not need to be specified in the where clause to update a row.
       RowVersioning = No
       # Show SystemTables
       # The driver will treat system tables as regular tables in SQLTables. This is good for Access so you can see system tables.
       ShowSystemTables = No
       # If true, the driver automatically uses declare cursor/fetch to handle SELECT statements and keeps 100 rows in a cache.
       Fetch = Yes
       # Bools as Char
       # Bools are mapped to SQL_CHAR, otherwise to SQL_BIT.
       BoolsAsChar = Yes
       # SSL mode
       SSLmode = Yes
       # Send tobackend on connection
       ConnSettings =
