In the PostgreSQL Todo wiki, Boyer-Moore string searching for LIKE is
mentioned as an outstanding item.
For the common and simple cases of find this string anywhere in another
string:
str LIKE '%foo%'
str ILIKE '%foo%'
position('foo' in str) > 0
Is Boyer-Moore string searching now used by any of these three?
I checked the PG documentation and found no info about this other than what
was in the Todo wiki, https://wiki.postgresql.org/wiki/Todo, under
Functions. Tom Lane gave a thumbs down to the idea back in 2008, but that
was a long time ago:
