[OPENJPA-1259] Postgres

• Type: Bug
• Status: Open
• Priority: Minor
• Resolution: Unresolved
• Affects Version/s: 2.0.0-M2
• Component/s: jdbc
• Environment: Os X, Linux, Postgres 8.[3|4], 8.[3|4] JDBC drivers
• Assignee: Unassigned

Description

When native sequence is set for Postgres in persistence.xml, i.e.

<property name="openjpa.Sequence" value="native(Allocate=500, Increment=1)"/>

subsequent schema synchronizations like "add" or "drop,add"

(i.e.:<property name="openjpa.jdbc.SynchronizeMappings" value="buildSchema(SchemaAction='add',primaryKeys=true,foreignKeys=true,indexes=true)"/>
or <property name="openjpa.jdbc.SynchronizeMappings" value="buildSchema(SchemaAction='drop,add',primaryKeys=true,foreignKeys=true,indexes=true)"/>

when some sequences are already there result in SQL exception since apparently the DB catalog for sequences is not checked against their existence:

Exception in thread "main" <openjpa-2.0.0-SNAPSHOT-r422266:805841 nonfatal general error> org.apache.openjpa.persistence.PersistenceException: ERROR: relation "someseqence" already exists

{stmnt 1582545914 CREATE SEQUENCE schema.somesequence START WITH 1 CACHE 500}

This prohibits updating schema without deletion of the existing sequences.
