Hi, I found an unreachable block during studing the PostgreSQL 7.0.2 by reading its souce code. Starting from line 1383 in postgres.c 1383 if (Verbose) 1384 { 1385 if (Verbose) 1386 { : 1389 } 1390 else 1391 { : // !! unreachable 1405 } 1406 } Can someone take a look of it? This shouldn't take long time to fix. Before this mail, I sent this problem to pgsql-hacker and found here is where I should send this mail. So, pleaes discard the mail I sent to pgsql-hacker. Sorry about that. -- Limin Liu
