                     String defaultDatabase,
                     String defaultSchema,

                     Map server,
                     IdentifierInputForm nameForm,
                     IdentifierProfile identifierProfile)

Same input, analyzed under an explicit identifier configuration.

The metadata this environment registers is indexed with identifierProfile, so the analysis that reads it back asks the catalog the same question it was filled with. A profile belonging to another vendor is not applied (IdentifierProfile.forVendorOr(gudusoft.gsqlparser.sqlenv.IdentifierProfile, gudusoft.gsqlparser.EDbVendor)); null means the vendor default.
