I got the following error
Error: diesel_guard::parse_error (link)
× Failed to parse SQL: Invalid statement: syntax error at or near "CREATE"
help: Check that your SQL syntax is valid Postgres
I fortunately knew which file I had just changed so I could find the error, but, even then, the file had 6 CREATE statements so it took me a minute to track down the issue.
It would be really nice to list both file name and line number on parse error.
