The application dies when insertion fails.

<p><font size="2">Hi Gurus,</font><p><font size="2">This has been bothered me for a couple of days. I wrote a postgres
dbapplication in perl which parses a syslog file and inserts some data into a table. I put the actual insertion in a
evalblock, so the application won't die when insertion fails. But it doesn't work as I expected. When it encounter a
"DBD::Pg::stexecute failed: ERROR:  Bad timestamp external representation 'Jan 11 18:05:50   at (eval 9) line 426,
<MSGS>line 1." error, the whole program die.</font><p><font size="2">I'm using DBD::Pg intereface, postgres
7.1.3.Here is the codes:</font><p><font

thatthe timestamp is not valid, but the excution should continue. Strange thing is that it didn't die right away. After
print"$@"prints out the error "DBD::Pg::st execute failed: ERROR:  Bad timestamp external representation 'Jan 11
18:05:50  at (eval 9) line 426, <MSGS> line 1." it dies.</font><p><font size="2">So what do I miss
