Query issue/8.0.1/Serendipity - Mailing list pgsql-sql

I have an 8.0.1 server running the Blogging software serendipity, and the 
following query fails with "relation e not defined", but it is on the first 
line:

"SELECT timestamp FROM serendipity_entries e, serendipity_category c,
serendipity_entrycat ec LEFT OUTER JOIN serendipity_entryproperties
ep_cache_extended ON (e.id = ep_cache_extended.entryid AND
ep_cache_extended.property = 'ep_cache_extended') LEFT OUTER JOIN
serendipity_entryproperties ep_cache_body ON (e.id = ep_cache_body.entryid
AND ep_cache_body.property = 'ep_cache_body') LEFT OUTER JOIN
serendipity_entryproperties ep_access ON (e.id = ep_access.entryid AND
ep_access.property = 'ep_access') LEFT JOIN serendipity_entryproperties
ep_sticky ON (e.id = ep_sticky.entryid AND ep_sticky.property =
'ep_is_sticky') WHERE e.timestamp >= 1109656800 AND e.timestamp <= 1112335200
AND e.timestamp <= 1110241185 AND e.isdraft = 'false' AND (ep_access.property
IS NULL OR ep_access.value = 'member' OR ep_access.value = 'public' OR
(ep_access.value = 'private' AND e.authorid = 1)) AND e.id = ec.entryid AND
c.categoryid = ec.categoryid AND c.category_left BETWEEN 3 AND 4"

The software is at:

here is the exact response from Pg:

ERROR:  relation "e" does not exist
serendipity=#  

What is wrong?

serendipity=# select version();                              version
