Hi,
I'm using the ltree module and located several problems, I think not all problems are
really ltree related but might be a pg_dump/pg_restore problem.
Here are the problems I've encountered:
* pg_restore tries to create a table with ltree and ltree[] datatypes before the type
itself is created, so it fails.
* several functions are already defined in template1, so "create database " will
restore these functions. pg_restore will try to restore those functions as well
and fails. Maybe "create or replace function" can be used here? I'm willing to do
this if it's ok.
* I've gist indices on ltree[] columns, and when pg_restore tries to restore it it
will report:
pg_restore: [archiver (db)] could not execute query: ERROR: data type ltree[] has
no default operator class for access method "gist"
You must specify an operator class for the index or define a
default operator class for the data type
It seems those extra functions for index support are not restored. Removing the
commit/end from ltree.sql and running it again (will report a lot of errors, but a few
inserts as well) will make this work again. However it requires a lot of DBA
assistance to restore.
All other problems are solvable by using "pg_restore -L" and using a modified archiv
index, but IMO this should work out of the box.
Best regards,
Mario Weilguni
