script to drop and build all indexes in database

PostgreSQL:9.2
OS: Linux
Does someone have a script that they would be willing to share that would:

1) Create a list of all indexes within database X

2) Loop for each index in list

3) Inside loop drop index then create index with concurrently

4) End loop

5) Exit script
I have been using the command, "REINDEX DATABASE somedatabename" , to rebuild all of my indexes on a production database used for web applications. But I believe while this is running late at night users are experiencing issues when they submit web requests that would write to tables that are being reindexed. I discovered that reindex does not allow for the use of concurrently as a parameter.

Suggestion:
It seems like it would be a good idea to add the parameter of concurrently to reindex.

Thanks so much,
