Subject: [GENERAL] @ operator
Hello, google nothing for @ operator =(, what does this mean field1 <@ ( subquery ) ?
ps: sorry for my English
Could be absolute-value operator for numeric data types,
or array (or range) inclusion operator.
See PG docs (and these docs should be your first option, before googling):
http://www.postgresql.org/docs/9.4/static/typeconv-oper.html

Igor Neyman
