I think the fact that identifiers fail to follow language-specific case folding rules is more a known gotcha than a desired property, but on principle I tend to agree that Turkish people would not be happy about the prospect of us changing the downcasing rule in a major release -- it would mean having to edit any affected application code as part of a pg_upgrade process, which is not great. Now you could say that this can be fixed by adding a GUC that preserves the old behavior, but generally we don't like that too much. The counter argument is that there are more future users than there are current users. -- Álvaro Herrera https://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services
