PostgreSQL Database Requirements

PostgreSQL Database Requirements

Use the following guidelines when you set up the database on PostgreSQL:
Privileges
Verify that the database user account has CREATE TABLE and CREATE VIEW privileges.
Disk Space
Ensure that PostgreSQL has sufficient disk space for the data files. By default, the data files are present in the following location:
<PostgreSQL installation directory>/data
Configuration Parameters
On the database, set the configuration parameters.
The following table lists the minimum and recommended values for the configuration parameters:
Parameter
Minimum Value
Recommended Value
max_connections
200
4000
shared_buffers
2 GB
16 GB
max_locks_per_transaction
1024
4000
max_wal_size
1 GB
8 GB
checkpoint_timeout

30 minutes
Configuring PostgreSQL for the PowerCenter repository
To configure a PostgreSQL database for the PowerCenter repository, set values for the PostgreSQL database host, port, and service name for the pg_service.conf file in the following format: 
[PCRS_DB_SERVICE_NAME]
host=Database host IP
port=Database port
dbname=PowerCenter repository database service name
Ensure that the entries for the [PCRS_DB_SERVICE_NAME] entry match the configuration for the PowerCenter Repository Service. To securely connect to PostgreSQL for the PowerCenter repository, set the security property along with the remaining required database properties in the pg_service.conf file in the following format:
sslmode=require
 Set the PGSERVICEFILE environment variable to the location of the pg_service.conf file. The pg_service.conf file contains the connection parameters for PostgreSQL database connection in the Informatica installation directory. For example, set the variable as follows:
Using a Bourne shell: 
$ export PGSERVICEFILE; PGSERVICEFILE=<pg_service.conf file 
directory>/pg_service.conf
Using a C shell: 
$ setenv PGSERVICEFILE <pg_service.conf file 
directory>/pg_service.conf
