Environment

VMware vCenter Site Recovery Manager 8.x

Cause

• The issue is caused as PG name has special characters like @ ! and spaces between the name

Resolution

Note: Stop the SRM service on both sites (Production and recovery) and take a back of the SRM DB

• Stop the SRM service from services.msc console 
• Backup SRM DB -https://techdocs.broadcom.com/us/en/vmware-cis/live-recovery/site-recovery-manager/8-6/site-recovery-manager-installation-and-configuration-8-6/creating-the-srm-database/back-up-and-restore-the-embedded-vpostgres-database.html
• Re-name PG and remove special characters and spaces if present.
