Hi,
I got an exception while upgrading from Base 2.4.3 to 2.4.5. It was
during dropping indexes using
"[basedir]/bin/dynamicdb.sh -v -dropindexes" command. The exceptions
message follows:
// some successful droppings
=================

I investigated a bit and found out that this index in fact exists. I
managed to drop it manually using psql with command:
DROP INDEX "dynamic"."D21886Filtercolumn"
Command without schema name prefix (DROP INDEX "D21886Filtercolumn")
doesn't work. I checked the index dropping code and I found out that in
net.sf.basedb.core.dbengine.PostgresDbEngine.getDropIndexSql() method
code(line 120) creating 'drop index query' uses only index name without
schema name prefix. That is why an exception is thrown.
I didn't find anything about adding dynamic schema to users search_path
in PostgreSql in Base2 requirements. Some of the code in the same
'problem causing' method adds schema prefix when dropping constraints,
so I consider this issue as a bug.
We are looking now for some work-around, like postgres search-path
setting and will post everything useful we find.
