The way to avoid too many parameters is not to fiddle and fidget until it accepts too many parameters, as too many parameters will be too many parameters no matter how you cut it. The way to avoid too many parameters is to not use too many parameters.

Perhaps you can avoid reading the file into a shell variable at all:

Code:
( printf "%s" "select name from table_name where cardnum in ('"
        cat parameters.txt
        printf "%s\n" "')" ) | databasecommand

execute

EXECUTE(7)							   SQL Commands 							EXECUTE(7)

NAME

       EXECUTE - execute a prepared query

SYNOPSIS

	  EXECUTE plan_name [ (parameter [, ...] ) ]

   INPUTS
       plan_name
	      The name of the prepared query to execute.

       parameter
	      The  actual  value  of a parameter to the prepared query.  This must be an expression yielding a value of a type compatible with the
	      data-type specified for this parameter position in the PREPARE statement that created the prepared query.

DESCRIPTION

       EXECUTE is used to execute a previously prepared query. Since prepared queries only exist for the duration of a session, the prepared query
       must have been created by a PREPARE statement executed earlier in the current session.

       If  the	PREPARE  statement  that created the query specified some parameters, a compatible set of parameters must be passed to the EXECUTE
       statement, or else an error is raised. Note that (unlike functions) prepared queries are not overloaded based on  the  type  or	number	of
       their parameters: the name of a prepared query must be unique within a database session.

       For more information on the creation and usage of prepared queries, see PREPARE [prepare(7)].

COMPATIBILITY

   SQL92
       SQL92  includes	an EXECUTE statement, but it is only for use in embedded SQL clients. The EXECUTE statement implemented by PostgreSQL also
       uses a somewhat different syntax.
