Setting up postgres on mac

This is a beginner blog.

1.) Install Postgres server.
Or, if it already installed; we can search (in mac )

Anirudhs-MacBook-Pro:~ anirudh$ mdfind postgres | grep include

2.) First time starting postgres server and initialise the space.
We need to initialise

Anirudhs-MacBook-Pro:bin anirudh$ ./initdb /usr/local/var/postgres -E utf8
The files belonging to this database system will be owned by user "anirudh".
This user must also own the server process.

The database cluster will be initialized with locales
  COLLATE:  C
  CTYPE:    UTF-8
  MESSAGES: C
  MONETARY: C
  NUMERIC:  C
  TIME:     C
initdb: could not find suitable text search configuration for locale "UTF-8"
The default text search configuration will be set to "simple".

Data page checksums are disabled.

WARNING: enabling "trust" authentication for local connections
You can change this by editing pg_hba.conf or using the option -A, or
--auth-local and --auth-host, the next time you run initdb.

Success. You can now start the database server using:

    ./postgres -D /usr/local/var/postgres
or
    ./pg_ctl -D /usr/local/var/postgres -l logfile start

3.)Start the server :

 ./postgres -D /usr/local/var/postgres
