psql script error handling

[James Neff <jneff(at)tethyshealth(dot)com>]

I have an sql script that I am trying to execute in psql client on the 
database itself.  The script is just a bunch (hundreds of thousands) of 
INSERT statements.

I don't know how, but I seem to have bad characters throughout my file 
and when I run the script it will of course error out complaining about 
the invalid character.  I figure out how many insert statements were 
successful and use sed to chop of those statements from the sql script 
file.  I then use VI and delete out the bad character and re-run the 
script. 

There's got to be a better way to do this.  Is there a way in a psql 
script to try to execute the INSERT statement and if theres a problem to 
dump it to a log file and go on with the others?

Thanks in advance,
James
