Yuck.

My suggestion would be to install the tsearch or tsearch2 module, and
modify the on-insert trigger to include the contents of all the fields
in your table.  There are examples in the tsearch readme, but you can
set the trigger on multiple columns.  Then that query would probably be
very fast and would turn into
select * from table where master_idx ## 'my|name|is|bill'
You can also do more powerful levels of grouping and boolean logic.
