Обсуждение: Feature request dblink: Security issue - dblink user+password parameters must be optional

When creating a view via DBLINK, the user=... and password=...
parameters shall be optional. If they are left out, then the current
user accessing the view shall be impersonated implicitely to the
"dblinked" database as well. Forcing anybody to hardcode a password
readable within the view definition should be an absolute DON'T!

Haven't found a better place to post this request. Hope the author of
dblink is reading it here, too. :-)

I think this will be properly fixed by SQL-MED connection handling in 8.4.

In older version maybe you can use wrapper function around dblink
that constructs per-user connect string.
