It seems this may have been resolved in recent versions. But I can confirm it is an issue in 8.0.13 in our production database. Works fine for me on 8.0.16 on local though.

Description: regexp_replace does not work when used in derived tables. How to repeat: Simply run the following query: SELECT test_col from (SELECT regexp_replace('http://test.com';, '(http://)';, '') test_col) t1 Returns blank value. Should instead return 'test.com' value.
