Tom Lane ebb0a20149 Keep track of the last active slot in the shared ProcState array, so ... that search loops only have to scan that far and not through all maxBackends entries. This eliminates a performance penalty for setting maxBackends much higher than the average number of active backends. Also, eliminate no-longer-used 'backend tag' concept. Remove setting of environment variables at backend start (except for CYR_RECODE), since none of them are being examined by the backend any longer.		25 years ago
