"""
|
|
Script for analysing the indexing process.
|
|
|
|
The script enables detailed logging for nested statements and then
|
|
runs the indexing process for teh given object. Detailed 'EXPLAIN ANALYSE'
|
|
information is printed for each executed query in the trigger. The
|
|
transaction is then rolled back, so that no actual changes to the database
|
|
happen. It also disables logging into the system log, so that the
|
|
log files are not cluttered.
