Postgresql Not working.. - Mailing list pgsql-general

i've been trying to find help everywhere..
Im new at postgresql and im running Postgresql on Mandrake 8.1 (or redhat)
and everytime i try to insert into a text field large text it will hang..

example..

Create table dodo (textfield text NULL);

Insert Into dodo (textfield) values('HUGEText');

//---------------------------------------------------------//

where HugeText = a web page html source or any big sized text data..  24 -
100 Kb size

now i know that Postgres had limitations with large text but wasnt that
fixed with toast.. but why then is my query timing out ONLY when i try to
insert large text..??

any help would be appreciated..
Thanks..
