re the database in our product for quite sometime.=0AOne of our customers r=
eported an issue with multiple entries for a field marked as primary key.=
=0A=A0=0AAfter investigation of the logs we found the multiple entires were=
 created during pg_restore and the primary key constraint on the field coul=
d not be created due to unique constraint violation.=0A=A0=0AAfter searchin=
g on internet I came across the Postgres BUG 8382 & 3231 & 7760 reported in=
 the past for this issue.=0A=A0=0AThe Postgres version on which the issue w=
as reported is 8.2.2=0AWe have upgraded our Postgres version to 9.0.4 in th=
e current product release and I would like to know whether the issue in dis=
cussion is fixed in Postgres 9.0.4?=0A=A0=0AThank you,=0AUmesh Kirdat
