Trying to work with your code - 
update table set name = 
substr( name,1,strpos(name, (REGEXP_MATCHES(name, E'\\(.+?\\)')) )-1 ) ||
substr( name,strpos(name, (REGEXP_MATCHES(name, E'\\(.+?\\)')) ) + 1 
,char_length(name))

I am trying to find what is there before the pattern and after the pattern 
and concatenating them . Please see documentation for proper use of 
substr,strpos,cahr_length etc. 

Regards,
Jayadevan
