It seems that the PG version of edit this page is broken.
I get:
Database operation "0or1row" failed (exception NSDB, "Query was not a statement returning rows.")
while executing
"ns_pg_bind 0or1row nsdb0 {
select etp__create_page(
:package_id,
:name,
:title,
:content_type
)
}"
("uplevel" body line 1)
invoked from within
On a fresh Postgres install of the latest tarball.
