I'm seeing this error on compilation:
Compiling file /Users/edward/.emacs.d/elpa/sqlformat-20210305.209/sqlformat.el at Mon Jun 20 19:27:40 2022

Compiling internal form(s) at Mon Jun 20 19:27:41 2022
Warning (bytecomp): function ‘sqlformat’ defined multiple times in this file
Still seems to work OK, but just wanted to post in case it's helpful. I only see defgroup sqlformat and defun sqlformat in sqlformat.el so I guess it's complaining about those being the same.
My emacs:
