I am setting up database connection for a system that has multiple lines. I am using postgreSQL and the PLCs on each line have the same IP address.Line 1 plc is 10.0.0.112, Line 2 plc is 10.0.0.112, Line 3 plc is 10.0.0.112, etc. Should there be any concern of data clashing?
Duplicate IPs on the same logical network is a bad idea.
Assuming there are other devices on each line that would also be duplicates, I'd recommend a NAT device of some sort on each line to provide a logical separation between them.
