Hallo,
in dev version 1.13.0 Dev (ver: REL-1_13_DEV-272-g451d464) when viewing or editing PL/pgSQL code, an SQL statement, containing CASE..END constructs makes the block grouping [(-)(+) blocks] think, that the END of the CASE is and END of the BEGIN block... and later grouping blocks are invalidly rendered afterwards.
With best regards,
