I moved from postgres 7.0.2 to 8.0.1,

in the 7.0.2 version I process the next query, and it succeed:

select ichar(letra_ascii) || '-' || substr('00000' ||num_factura,length

(num_factura)+1,5) as factura from facturas

but in 8.0.1 it outputs the next error:

ERROR: not exist the function ichar(integer)
HINT: any function match with the arguments types.
Add explicit cast of types

[ digs in archives... ] Looks like we renamed ichar() to chr() quite
some time ago.

If you only have one compatability problem, I'd be surprised.

I'll point you to Tom Lane's thoughts on this back in 2000:
