The following illustrates the problem (removing double quotes from a string):
js=# select regexp_replace(regexp_replace( '"University of Cape Town"', '^"', ''),'"$', ''); regexp_replace ------------------------- University of Cape Town (1 row)
js=# trim(both '"' from '"University of Cape Town"'); ERROR: syntax error at or near "trim" LINE 1: trim(both '"' from '"University of Cape Town"');
Example from the documentation:
js=# trim(both 'xyz' from 'yxTomxx'); ERROR: syntax error at or near "trim" LINE 1: trim(both 'xyz' from 'yxTomxx'); ^
I would think that "trim" if it works in this case would be a cheaper function than using rexexp_replace twice.
Or is there another way?
