Indexes on Arrays

Hello everyone.  Hopefully someone can give me an answer and workaround on
this...

I have a table with an array like so:
create table foo (    id    int4,    names    varchar(80)[]);

and would like to place an index on name[1].  I try
create table foo_idx1 on foo (names[1]);

but I get...
ERROR:  parser: parse error at or near "["

Thoughts and suggestions are welcome.
