This triggers a new warning for me (gcc-10):
/home/andres/src/postgresql/src/backend/executor/nodeLimit.c: In function ‘ExecLimit’:
/home/andres/src/postgresql/src/backend/executor/nodeLimit.c:136:7: warning: this statement may fall through [-Wimplicit-fallthrough=]
136 | if (ScanDirectionIsForward(direction))
| ^
/home/andres/src/postgresql/src/backend/executor/nodeLimit.c:216:3: note: here
216 | case LIMIT_WINDOWEND_TIES:
| ^~~~
I've not looked at it in any sort of detail, but it looks like it might
be a false positive, with the "fall-through" comment not being
sufficient to quiesce the compiler?
Cosmetically I would agree that falling through to the next case" a few
blocks deep inside a case: isn't the prettiest...
