PostGres Expert Needed -2

Please read this post in its entirety before bidding.. 1.) DO NOT RESPOND if you are NOT an expert with PostgreSQL 2.) DO NOT RESPOND If your profile does not have anything about architecting or supporting a PostgreSQL Database 3.) I will not be able to send you anything from the database, everything will be done via screen sharing. It will be a collaborative session with my engineers. If this is not acceptable DO NOT RESPOND I need a person that is an expert with PostgreSQL to help us troubleshoot an issue with a database upgrade and to help us with performance tuning of the database and server. Our current system we need assistance on is: CentOS Linux release 7.2.1511 (Core) psql (PostgreSQL) 9.4.9 The issue we are experiencing is: When trying to create a Foreign key Constraint from a newly created table (FOO) to a certain existing table (BAR) the process goes into waiting. We are able to successfully create foreign keys to any other table except this one, For example table FOO with a Foreign key to BUU works successfully. When trying to reindex BAR the process goes into waiting. I believe the table BAR is corrupt, although I can successfully select from the table.
