In post #8, sed under while loop should be (-e not really needed here):
Code:
sed "s/$SEARCH/$REPLACE/" sourcefile

Also as mentioed in post #9, sed under while, will run for each search/replace pair in the control file (source file being processed that many times, that is why output is repeated that many times), so you need to use -i option if supported.
Code:
sed -i "s/$SEARCH/$REPLACE/" sourcefile

This will modify source file itself.
I believe in such scenarios (where fields in one file are being modified based on values of fields in another file), awk provides better solutions.

drop_text_search_template

DROP TEXT SEARCH 
TEMPLATE(7)					   SQL Commands 				      DROP TEXT SEARCH TEMPLATE(7)

NAME

       DROP TEXT SEARCH TEMPLATE - remove a text search template

SYNOPSIS

       DROP TEXT SEARCH TEMPLATE [ IF EXISTS ] name [ CASCADE | RESTRICT ]

DESCRIPTION

       DROP TEXT SEARCH TEMPLATE drops an existing text search template. You must be a superuser to use this command.

PARAMETERS

       IF EXISTS
	      Do not throw an error if the text search template does not exist.  A notice is issued in this case.

       name   The name (optionally schema-qualified) of an existing text search template.

       CASCADE
	      Automatically drop objects that depend on the text search template.

       RESTRICT
	      Refuse to drop the text search template if any objects depend on it.  This is the default.

EXAMPLES

       Remove the text search template thesaurus:

       DROP TEXT SEARCH TEMPLATE thesaurus;

       This command will not succeed if there are any existing text search dictionaries that use the template. Add CASCADE to drop such dictionar-
       ies along with the template.

COMPATIBILITY

       There is no DROP TEXT SEARCH TEMPLATE statement in the SQL standard.
