Using regex in WHERE in Postgres

Question

I currently have the the following query:

select regexp_matches(name, \'foo\') from table;

How can I rewrite this so that the regex is in t

Answer 1

Just use match operator there:

select * from table where name ~ 'foo';

Answer 2

Write instead:

select * from table where name ~ 'foo'

The '~' operator produces a boolean result for whether the regex matches or not rather than extracting the matching subgroups.
