Homebrew-ed Postgresql: "Export error: Failed to execute pg_dump"

Problem to troubleshoot

Export error: Failed to execute pg_dump (given path in your conf/config.inc.php : /usr/bin/pg_dump). Please, fix this path in your configuration and relog.

Postgres phppgadmin: Export error

I am new to postgresql database,
and recently I have a chance to play with this technology and at the meantime, I have been facing newbie issues with it.

Since I won't using this tool for a long time, it's better to record down the troubleshooting note for future in the simple way.

I use homebrew to install postgresql and phppgadmin.

As said in the error message, we'll need to edit conf/config.inc.php in order to get it fixed.

1) find your config.inc.php with "mdfind -name config.inc.php"

search for config.inc.php file

2) Find your pg_dump binary file path with "which pg_dump"

pg_dump location

3) Place correct path to "pg_dump" configuration

4) Once you done steps above, remember to relogin your user in phppgadmin for changes above to take effect.
