I attached the result of this view that is run on the database after "make installcheck" just for reference.Some comments: I think we can use pgstat_* instead of pgstat* for code consistency. +static HTAB *pgStatBackendSql = NULL; How about *pgstat_backend_sql +HTAB *pgStatSql = NULL; How about *pgstat_sql Changed. +static void pgstat_recv_sqlstmt(PgStat_MsgSqlstmt * msg, int len); How about PgStat_MsgSqlstmt *msg instead of PgStat_MsgSqlstmt * msg Added the typdef into typdef.list file so this problem never occurs. +typedef struct PgStatSqlstmtEntry How about PgStat_SqlstmtEntry +typedef struct PgStatMsgSqlstmt How about PgStat_MsgSqlstmt changed. Updated patch is attached.
The updated patch gives following error. Error:../../../../src/include/pgstat.h:557: error: ‘PgStatSqlstmtEntry’ undeclared here (not in a function)
- ((PGSTAT_MSG_PAYLOAD - sizeof(int)) / sizeof(PgStatSqlstmtEntry)) + ((PGSTAT_MSG_PAYLOAD - sizeof(int)) / sizeof(PgStat_SqlstmtEntry)) The attached patch fixed the error. Regards, Vinayak Pokale
