Ltree usage..

Hi Oleg,

I am trying to use contrib/ltree for one of my applications.

the query below works fine for me.

Qry1: SELECT path from unified_data where path ~ '*.180.*' and path ~ '*.1.*';

is there any way of compacting it for example

Qry2: SELECT path from unified_data where path ~ '*.180.*' or path ~ '*.1.*'; is better
written as
Qry3: SELECT path from unified_data where path ~ '*.180|1.*' ;

also is qry3 better to Qry2 in terms of performance?

regds
