You mean, if it's going to be translated directly in sql anytime soon? The
function has been around for ... uh..
don't know exactly when, it was there 8 years ago when I going the
GeoServer development.
Translating filter functions in sql has never been a priority, I just did
some work a few years ago to show
that how it could have been done to a group of other devs that was
complaning about lack of
function translation support, whist stopped the complaints...
but did not result in them implementing the translation for the other
functions ;-)
I can point you to the code that does the translation, if you are
interested in trying to add support
for the strMatches function?
It can be done here:
https://github.com/geotools/geotools/blob/master/modules/plugin/jdbc/jdbc-postgis/src/main/java/org/geotools/data/postgis/FilterToSqlHelper.java#L468
As said, the tricky part is finding the differences in syntax between the
java one and the postgresql
one, and translating them.
