It's simpler to use sql to do this. Can you restore the table?
First you need to trim the \n and spaces:
andy=# insert into junk values (E'GW-22');
INSERT 0 1
andy=# insert into junk values (E'GW-22 \n');
INSERT 0 1
andy=# insert into junk values (E'GW-22 \n');
Here are three records, with spaces and CR's.
Trim it up:
andy=# select '['|| rtrim(trim(trailing E'\n' from a)) || ']' from junk;
?column?
----------
[GW-22]
[GW-22]
[GW-22]
(3 rows)
If you have a unique index you'll wanna drop it first. Once you get
that done, we can remove the dups.
