I should have included a better example - sorry - here is the real file:

create table "informix".esc_acct
(
fi_id decimal(9,0) not null ,
ea_nbr char(14) not null ,
rc_svcg_st_cd char(2) not null ,
ea_type_nm char(8) not null ,
ea_closd_dt date,
primary key (fi_id,ea_nbr) constraint "informix".pk_esc_acct
) extent size 12 next size 8 lock mode page ;
revoke all on "informix".esc_acct from "public" as "informix";

alter table "informix".esc_acct add constraint (foreign key (fi_id)
references "informix".fi constraint "informix".fk_esc_acct_from_fi);

When I ran Franklin's script I got:

nawk '/alter table/{f=1}/;$/{f=0;next}!f' esc_acct_resize.sql

{ TABLE "informix".esc_acct row size = 34 number of columns = 5 index size = 36 }
create table "informix".esc_acct
(
fi_id decimal(9,0) not null ,
ea_nbr char(14) not null ,
rc_svcg_st_cd char(2) not null ,
ea_type_nm char(8) not null ,
ea_closd_dt date,
primary key (fi_id,ea_nbr) constraint "informix".pk_esc_acct

So it trunc'd off too much... I am messing with the cmds that Franklin sent me.

Thanks,

Mike

drop_table

DROP 
TABLE(7)						  PostgreSQL 9.2.7 Documentation					     DROP TABLE(7)

NAME

       DROP_TABLE - remove a table

SYNOPSIS

       DROP TABLE [ IF EXISTS ] name [, ...] [ CASCADE | RESTRICT ]

DESCRIPTION

       DROP TABLE removes tables from the database. Only the table owner, the schema owner, and superuser can drop a table. To empty a table of
       rows without destroying the table, use DELETE(7) or TRUNCATE(7).

       DROP TABLE always removes any indexes, rules, triggers, and constraints that exist for the target table. However, to drop a table that is
       referenced by a view or a foreign-key constraint of another table, CASCADE must be specified. (CASCADE will remove a dependent view
       entirely, but in the foreign-key case it will only remove the foreign-key constraint, not the other table entirely.)

PARAMETERS

       IF EXISTS
	   Do not throw an error if the table does not exist. A notice is issued in this case.

       name
	   The name (optionally schema-qualified) of the table to drop.

       CASCADE
	   Automatically drop objects that depend on the table (such as views).

       RESTRICT
	   Refuse to drop the table if any objects depend on it. This is the default.

EXAMPLES

       To destroy two tables, films and distributors:

	   DROP TABLE films, distributors;

COMPATIBILITY

       This command conforms to the SQL standard, except that the standard only allows one table to be dropped per command, and apart from the IF
       EXISTS option, which is a PostgreSQL extension.
