I need to clarify step 3 and 5.
suppose I find pattern A on line 25 of the input text file, now I need to find the first occurence of pattern B from lines 25 through 1 of the file - in reverse. Say pattern B occurs on line 20 and line 15 and line 10. I need line 20, but not lines 15 & 10.
Thanks.

NAME
DROP TEXT SEARCH CONFIGURATION - remove a text search configuration
SYNOPSIS
DROP TEXT SEARCH CONFIGURATION [ IF EXISTS ] name [ CASCADE | RESTRICT ]
DESCRIPTION
DROP TEXT SEARCH CONFIGURATION drops an existing text search configuration. To execute this command you must be the owner of the configura-
tion.
PARAMETERS
IF EXISTS
Do not throw an error if the text search configuration does not exist. A notice is issued in this case.
name The name (optionally schema-qualified) of an existing text search configuration.
CASCADE
Automatically drop objects that depend on the text search configuration.
RESTRICT
Refuse to drop the text search configuration if any objects depend on it. This is the default.
EXAMPLES
Remove the text search configuration my_english:
DROP TEXT SEARCH CONFIGURATION my_english;
This command will not succeed if there are any existing indexes that reference the configuration in to_tsvector calls. Add CASCADE to drop
such indexes along with the text search configuration.
COMPATIBILITY
