[GENERAL] Numeric Sorting

[Chester]

Hi

Just a quick one, I have been around Postgres for a little while and 
have never found an answer to this.

Can you numerically sort a set of integers stored in a char column, I 
guess change the cast of the column for the "sort by" process.

and, if you can how...Unfortunatly I  have no choice in  the current 
"char" definition of  the column.

The version of PSQL is 8.+

TIA

Regards

C
