[Hummmm, wonder why it didn't have pgsql-interfaces in
the reply-to]


You can use pg_result to get any error info. For
example:

set han [pg_connect ...]

set result [pg_exec $han "SELECT * FROM bogus_table"]

set stat [pg_result $result -status]

if {$stat ne "PGRES_TUPLES_OK"} {

    puts "GOT ERROR: [pg_result $result -error]"
}


HTH,
