Step 3: Install POWA Software

[root@localhost powa-REL_1_1]# export PATH=/opt/PostgreSQL/9.3/bin:$PATH
[root@localhost powa-REL_1_1]# export LD_LIBRARY_PATH=/opt/PostgreSQL/9.3/lib:$LD_LIBRARY_PATH
[root@localhost powa-REL_1_1]# make install

/bin/mkdir -p '/opt/PostgreSQL/9.3/share/postgresql/extension'
/bin/mkdir -p '/opt/PostgreSQL/9.3/share/postgresql/extension'
/bin/mkdir -p '/opt/PostgreSQL/9.3/lib/postgresql'
/bin/mkdir -p '/opt/PostgreSQL/9.3/doc/postgresql/extension'
/usr/bin/install -c -m 644 ./powa.control '/opt/PostgreSQL/9.3/share/postgresql/extension/'
/usr/bin/install -c -m 644 ./powa--1.0.sql ./powa--1.1.sql  '/opt/PostgreSQL/9.3/share/postgresql/extension/'
/usr/bin/install -c -m 755  powa.so '/opt/PostgreSQL/9.3/lib/postgresql/'
/usr/bin/install -c -m 644 ./README.md '/opt/PostgreSQL/9.3/doc/postgresql/extension/'

Step 4: Create a POWA database & Create requires extensions

-bash-4.1$ /opt/PostgreSQL/9.3/bin/psql -p 5435
Password: 
psql.bin (9.3.5)
Type "help" for help.
postgres=# create database powa;
CREATE DATABASE
postgres=# \c powa 
You are now connected to database "powa" as user "postgres".
powa=# create extension pg_stat_statements ;
CREATE EXTENSION
powa=# create extension btree_gist ;
CREATE EXTENSION
powa=# create extension powa;
CREATE EXTENSION
powa=# \dt
                      List of relations
 Schema |              Name               | Type  |  Owner   
--------+---------------------------------+-------+----------
 public | powa_functions                  | table | postgres
 public | powa_last_aggregation           | table | postgres
 public | powa_last_purge                 | table | postgres
 public | powa_statements                 | table | postgres
 public | powa_statements_history         | table | postgres
 public | powa_statements_history_current | table | postgres
(6 rows)

Step 5:  add "power" & "pg_stat_statements" in the shared_preload_libraries in postgresql.conf file

-bash-4.1$ more /opt/PostgreSQL/9.3/data/postgresql.conf |grep shared_preload
# Note:  Increasing max_prepared_transactions costs ~600 bytes of shared memory
shared_preload_libraries = 'powa,pg_stat_statements' # (change requires restart)


-bash-4.1$ /opt/PostgreSQL/9.3/bin/pg_ctl -D /opt/PostgreSQL/9.3/data/ start
server starting
