No, you need to install the extension pg_stat_statements:

http://www.postgresql.org/docs/current/static/pgstatstatements.html

are you referring below Tool ?

PoWA is PostgreSQL Workload Analyzer that gathers performance stats and provides real-time charts and graph to help monitor and tune your PostgreSQL servers. It is similar to Oracle AWR or SQL Server MDW.

No, you need to install the extension pg_stat_statements:

http://www.postgresql.org/docs/current/static/pgstatstatements.html
http://www.postgresql.org/docs/current/static/sql-createextension.html
 

You also need the extensions plpgsql (which should already be installed) and btree_gist.

When installing the powa extension (CREATE EXTENSION powa;), postgres will warn you of missing dependancy if any.

You can also refer to the installation documentation (https://github.com/dalibo/powa/blob/master/README.md).

You need to Install "unzip" utility. Once you installed "unzip" utility,you can extract in "/tmp" directory.

for Debian and Ubuntu:
1
apt-get install unzip

for Red Hat Linux/Fedora/CentOS users:

1
yum install unzip

You need to Install "unzip" utility. Once you installed "unzip" utility,you can extract in "/tmp" directory.

As an alternative to the "unzip" command, the "jar" command from the Java SDK can be used. Java "jar" files are simply zip files. And the jar command can list, create, and extract from jar files.

jar xf powa-REL_1_1.zip # unzip

===

jar cf new.file.zip set.txt of.txt subdir/files.bin # create new

jar lf new.file.zip # list contents
