Bug reference:      13777

PostgreSQL version: 9.3.6
Operating system:   RedHat 6.5 x86
Description:

We are experiencing a "bug" that we had not noticed, the releases 9.3.3 and
9.3.6.
  1) a migration via dump / restore, version 9.0.7 to version 9.3.6 was
carried out, and after seven months in one of the tables, which had 8 FKs,
these FKs began to no longer treat referential integrity, ie, it was as if
the FKs did not exist;
  2) the development platform, release 9.3.3, a database was created
(dbadmin-new) using, as a template, another existing database (dbadmin). And
then charges through inserts have not been validated by FKs. It was found
that all FKs exist. However, FKs not restricted any inclusion of information
without integrity. Instructions for creating the database was:
    CREATE DATABASE 'dbadmin-new' WITH TEMPLATE 'dbadmin' OWNER 'postgres'
TABLESPACE = 'homolog';

   Our PostgreSQL been compiled in accordance with the parameter set of the
following:
    * For 9.3.6 - production platform ==> CONFIGURE = '--prefix = / usr /
local / pgsql-9.3.6' --with-perl '' --with-python '' --with- tcl ''
--with-tclconfig = / usr / lib64 '' --with-krb5 '' --with-openssl ''
--with-pam '' --with-ldap '' --with-libxml '' --with-libxslt '
    * For 9.3.3 - plataform development ==> CONFIGURE = '--prefix'
'/usr/local/pgsql-9.3.3' '--with-perl' '--with-python' '--with -tcl ''
--with-tclconfig = / usr / lib64 '' --with-krb5 '' --with-openssl ''
--with-pam '' --with-ldap '' --with-libxml '--with-libxslt'

   Our production platform is grounded in PostgreSQL cluster with a total of
5 nodes, with streaming replication, and I am the one who created and
manages all of these platforms.

   You could refer, please, this e-mail to the development team to see if
anyone else has experienced this situation? Sought I and an architect,
references in this 'bug' but did not find anything or the forums, and even
the Internet in general.

  Thanks.
