It seems that pg_dump (in 6.4.2) still has problem with quoting \ and ' when they appears together.
The following example illustrates this.


terekhov=> create table test (i int, t text);
CREATE
terekhov=> insert into test values (1,'');
INSERT 19066 1
terekhov=> insert into test values (2,'abcd');
INSERT 19067 1
terekhov=> insert into test values (3,'\\');
INSERT 19068 1
terekhov=> insert into test values (4,'\'');
INSERT 19069 1
terekhov=> insert into test values (5,'\\\'');
INSERT 19070 1
terekhov=> select * from test;
i|t   
-+----
1|    
2|abcd
3|\   
4|'   
5|\'  
(5 rows)

terekhov=> \q
terekhov(575)~>pg_dump -d -D -f ter.db terekhov
terekhov(576)~>cat ter.db
CREATE TABLE "test" (
	"i" int4,
	"t" text);
INSERT INTO "test" ("i","t") values (1,'');
INSERT INTO "test" ("i","t") values (2,'abcd');
INSERT INTO "test" ("i","t") values (3,'\');
INSERT INTO "test" ("i","t") values (4,'''');
INSERT INTO "test" ("i","t") values (5,'\''');

		   Wrong quoting here ----^
