AFAICR, path with shell-sensitive characters ($ ? * ...) which was
breaking something somewhere.

Hmmm. That is the problem of CreateTableSpace. From an SQL perspective,
escaping is required. If the command fails later, that is the problem of
the command implementation, but otherwise this is just a plain syntax
error at the SQL level.

Yes, I looked at it and imported the window-specific function to handle
the path. It does not do anything about escaping.

As said, this is required for SQL, or you must know that there are no
single quotes in the string.

Sure. It is probably buggy there too.

Hmmm. The committer is right by definition. Here is a version without
escaping but with a comment instead.
