Good Linux connector forPostgreSQL to C++

NOTE: Video and source code examples posted here https://quantlabs.net/blog/2015/08/postgresql-demo-with-cpp-on-ubuntu-linux/

Please see my video below to walk you through this process

I am now faced with this dilemma. There was a decent one a few years ago for C++ but I need an updated one to keep up with version changes in Postgres. Here is what I found:

http://stackoverflow.com/questions/1138503/good-c-c-connector-library-for-postgresql

http://www.tutorialspoint.com/postgresql/postgresql_c_cpp.htm

For the above link: use sudo ./configure (if you have permission access problems so run ‘sudo’ as well)

This is where my pg_hba.conf installed:

./etc/postgresql/9.3/main/pg_hba.conf

Create a PostgreSQL user with password and database to connect with as described here:

http://www.postgresql.org/docs/8.0/static/sql-alteruser.html

Start Postgres as explained here:

https://www.digitalocean.com/community/tutorials/how-to-install-and-use-postgresql-on-ubuntu-14-04

In a terminal run:

sudo -i -u postgres

psql

I create a new user within Postgres and update connection changes in the C++ files:

 

New

CREATE USER test WITH PASSWORD ‘test123’;

You could also create a database user or table via:

http://www.cyberciti.biz/faq/howto-add-postgresql-user-account/

new Ubuntu Linux users pgtest or pgtest with password Hello123_

In Postgres:
CREATE USER pgtest WITH PASSWORD ‘Hello123_’;
CREATE USER testpg WITH PASSWORD ‘Hello123_’;
CREATE DATABASE testdb
GRANT ALL PRIVILEGES ON DATABASE testdb to testpg;

THen
root@ubuntu:~# su – testpg
testpg@ubuntu:~$ psql -d testdb -U testpg
psql (9.3.9)
