> PostgresDictionary should set "63" (or something correct) as "maxAutoAssignNameLength", in order to let DBDictionary#getGeneratedKeySequenceName() generate correct names for IDENTITY sequences.
> OpenJPA trims IDENTITY sequence names longer than 32 characters, while PostgreSQL uses longer names for BIGSERIAL sequences. So, persisting entities with @Id column with GenerationType.IDENTITY often results in a database error such as :
> org.apache.openjpa.lib.jdbc.ReportingSQLException: ERROR: relation "x_school_membershi_entityid_seq" does not exist {prepstmnt 2398193 SELECT CURRVAL(X_SCHOOL_TRANSFER_entityId_SEQ')} [code=0, state=42P01]
> The followings are the examples. "OK"s are the sequence names which PostgreSQL uses. "NG"s are those which OpenJPA attempts to use.
> Ex.1 -
> Table : X_SCHOOL_TRANSFER_EVENT
> BIGSERIAL Column : ENTITYID
> OK : X_SCHOOL_TRANSFER_EVENT_ENTITY_ID_SEQ
> NG : 'X_SCHOOL_TRANSFER__ENTITYID_SEQ
> Ex.2 -
> Table : X_SCHOOL_MEMBERSHIP
> BIGSERIAL Column : ENTITYID
> OK : X_SCHOOL_MEMBERSHIP_ENTITYID_SEQ
> NG : X_SCHOOL_MEMBERSHI_ENTITYID_SEQ
