This page will deal with the  programming in C, C++, Embedded C, JAVA. for Postgres SQL server, Postgres function modules, etc.

When you compile your programs in C or C++, you see this error during execution:

Process terminated by SIGSEGV
core dumped
SYS1808:
The process has stopped. The software diagnostic
code (exception code) is  0005.

This error is caused by pq.dll environment runtime. For solving this problem you can:

1: create a script like psql.cmd; (substutite psql.exe with the name of your application
2: set environment variable PGUSER:
        set pguser=user
user is an user name created by psql monitor with "create user" statement or with createuser.cmd utility

In a network environment you must set the IP workstation in \pgsqldata\pg_hba.conf

File format:
host    dbname    ip_address    address_mask    authtype
For field authtype see pg_hba.conf file in \pgsqldata directory

Example:
host    account    192.168.0.0    255.255.255.0    trust
This example allow all users from 192.168.0.x hosts to connect to account database
