Quotes and casting together are not necessary.
Either of these will work:
lid = '457' and puerta = '10'
lid = 457::int2 and puerta = 10::int2
I'd choose "lid = 457::int2" since it's telling PG what the datatype
is, whereas with lid = '457', PG must figure it out.

After seeing all the viruses, trojan horses, worms and Reply
mails from stupidly-configured anti-virus software that's been
hurled upon the internet for the last 3 years, and the
time/money that is spent proteting against said viruses, trojan
horses & worms, I can only conclude that Microsoft is dangerous
to the internet and American commerce, and it's software should
be banned.
