that's the best thing I came up with:

select * from regexp_replace(
strip(
to_tsvector(
'<a:A href="http://www.google.com">pippo</a> pluto gigio'
))::text,
'\'([^\']*)\'','\\1:A','g');

This actually exploit the parser and you can specify the
configuration.

It would still be nice to be able to directly work with tsvector
and tsquery so people could exploit the parser, lexer etc... and
recycle the config.

I'd thinking something in the line of

for lex in select * from to_tsvector('jsjdjd fdsds')

would be nice.
