Re: reinitialize a sequence?

Following up to myself:

There is in fact a bug in 7.0.2 that's been fixed in 7.0.3 which causes
my select below not to work. The name of the sequence is now stored
with double quotes around it, to handle the mixed case names problem,
so the query needs to look like (untested: note added double quote to
last where clause):

select 'SELECT setval(\'"' ||        substr(adsrc,10,(length(adsrc) - 17)) ||     '"\', max("' || attname || '")) FROM
"'||     relname || '";'     from pg_class c,          pg_attribute a,          pg_attrdef d     where c.oid=d.adrelid
and          a.attrelid=c.oid and           d.adnum=a.attnum and           d.adsrc ~ ('nextval\\(\'"'||relname);
