case sensititvity bug in foreign keys on cygwin

Configuration:
Windows 2000 Server
cygwin 2.78.2.9
PostgreSQL 7.1.3
psqlODBC 7.1.8
pgAdmin II 1.1.66

Bug:
Capital letters cannot be used in column names used in foreign key
constraints

All Smalls succeeds:

-- Table: significance
CREATE TABLE "significance" (
"significanceid" int4 NOT NULL,
"desc" varchar(255),
CONSTRAINT "pk_significance" PRIMARY KEY ("significanceid"));

-- Table: primaryword
CREATE TABLE "primaryword" (
"exerciseid" int4 NOT NULL,
"significanceid" int4 NOT NULL,
CONSTRAINT "pk_primaryword" PRIMARY KEY ("exerciseid"),
CONSTRAINT "fk_primaryword_significance" FOREIGN KEY
(significanceid) REFERENCES "significance" (significanceid) );

With just the foreign table name capitalized, it also succeeds:
-- Table: Significance
CREATE TABLE "Significance" (
"significanceid" int4 NOT NULL,
"desc" varchar(255),
CONSTRAINT "pk_significance" PRIMARY KEY ("significanceid"));

-- Table: primaryword
CREATE TABLE "primaryword" (
"exerciseid" int4 NOT NULL,
"significanceid" int4 NOT NULL,
CONSTRAINT "pk_primaryword" PRIMARY KEY ("exerciseid"),
CONSTRAINT "fk_primaryword_significance" FOREIGN KEY
(significanceid) REFERENCES "Significance" (significanceid) );

Capitalizing just the foreign column name fails with what seems to be an
incorrect error:
-- Table: significance
CREATE TABLE "significance" (
"Significanceid" int4 NOT NULL,
"desc" varchar(255),
CONSTRAINT "pk_significance" PRIMARY KEY ("Significanceid"));

-- Table: primaryword
CREATE TABLE "primaryword" (
"exerciseid" int4 NOT NULL,
"significanceid" int4 NOT NULL,
CONSTRAINT "pk_primaryword" PRIMARY KEY ("exerciseid"),
CONSTRAINT "fk_primaryword_significance" FOREIGN KEY
(significanceid) REFERENCES "significance" (Significanceid) );

Fails with error
Description: Error while executing the query;
Error: UNIQUE constraint matching given keys for refernced table
"significance" not found

Capitalizing just the child column name fails :
-- Table: Significance
CREATE TABLE "significance" (
"significanceid" int4 NOT NULL,
"desc" varchar(255),
CONSTRAINT "pk_significance" PRIMARY KEY ("significanceid"));

-- Table: primaryword
CREATE TABLE "primaryword" (
"exerciseid" int4 NOT NULL,
"Significanceid" int4 NOT NULL,
CONSTRAINT "pk_primaryword" PRIMARY KEY ("exerciseid"),
CONSTRAINT "fk_primaryword_significance" FOREIGN KEY
(Significanceid) REFERENCES "significance" (significanceid) );

With the following error:
Description: Error while executing the query;
Error: Columns referenced in foreign key constraint not found

I could not get foreign keys to succeed if there were any caps in the column
names, although caps in primary key constraints seems to work just fine.
