This is Vimal from WIpro. We are using Postgres 14 , while connecting postgres from application we are getting "Could not open R2DBC Connection for transaction;" error in pod . We have increased the max number of connections in postgres from 100 to 1000 , still we are facing the same error.
I have pasted below the error for reference. Please help us on this issue
Thanks,
Vimal.
