You will say that there are other possibilities. Yes - but I am trying

You are passing the literal value table_name as the table, and
column_name as the column.
You need to concatenate the substituted values onto the string with the ||

If this is PPAS,
try the postgresql official rpm package for centos 5：

or build your own from source.
