Thanks John... It solved my problem!!!

I'm planning the migration to 11.7 for the next months.

Regards,
Alberto.

In short you are getting the wrong like operator to execute. My examp=
le
was very precise. If you change the column types and cast operators th=
en
different things will happen. I had the data stored in a column of typ=
e
ichar
and remove the default casts.

Have you removed the default casts?? You will have to play around to
ensure the operator you get is the correct one.

you might try
select * from tbdominiotiss where like( descricao::ichar,
"%procedimento%"::char(20) )

or what ever operators you defined the function with.
