Please refer to PostgreSQL documentation to download necessary database driver for the corresponding platform.
For some additional information please refer to: installing unixODBC.
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 = Require
# Send to backend on connection
ConnSettings =
