I have a bug reported on the Debian package of 6.3.2:
> videotapes=> grant all on tapes to www-data;
> ERROR: aclparse: non-existent user "www"
It is, in fact, impossible to create the user www-data:
template1=> create user www-data;
ERROR: parser: parse error at or near "-"
template1=> create user 'www-data';
ERROR: parser: parse error at or near "'"
So there are two problems:
1. The error message
`ERROR: aclparse: non-existent user "www"'
is incorrect. The parser should actually object to the `-' character; it
appears to be silently dropping the `-data'.
2. The range of possible user names is not the same as the range of possible
Unix login names. However, the manual pages do not define what characters
are valid. The SQL standard is silent on this point; it simply regards
the current user name as an identifier supplied by the system. On the
other hand, it is clear that PostgreSQL regards a user name as an SQL
identifier, so that there is no distinction of case and no punctuation
characters are allowed.
Is it possible to make the parser accept the full range of Unix login names,
including some punctuation characters and upper- and lower-case letters?
