Reported lengths of char fields - psqlODBC - Mailing list pgsql-odbc

Environment:

Linux Mint 18.3 x64 (base on Ubuntu 16.04 package base)

Postgresql v 9.5.14

unixODBC v2.3.1-4.1

psqlODBC  v1:09.03.0300-1

I created a simple table containing one column of type  character (n).  When I ask for the width of the column via (ODBC)SQLColAttribute function, it answers (n*6) , so if defined as character(1) the call reports length 6, character(2) reports 12, character(4) reports 24, etc. 

I see the same kind of results when using a varchar(n) field (character varying (2), etc  ) as well .

Is this expected, or am I doing something wrong?

Thanks,

Bob
