Обсуждение: Mysterious 7.0.3 error
Greetings! We have a script updating our database with thousands of entries on a daily basis. To speed up processing, we drop a consistency check trigger before the update and recreate it afterwards. Occasionally, we get the following, even though the database has no other live connections, and the trigger drop is the first statement: drop trigger rprices_insupdel on rprices; DROP ERROR: RelationClearRelation: relation 160298 modified while in use Any pointers most appreciated! -- Camm Maguire camm@enhanced.com ========================================================================== "The earth is but one country, and mankind its citizens." -- Baha'u'llah

Are you doing other schema changes (like other instances of this script)
in parallel? Or vacuums of system tables? Those are the cases I recall
that might trigger this problem.

Live with it until 7.1 :-(.
