Hmm,
15:59[mira]:~/app/egcs/obj>psql test
Welcome to the POSTGRESQL interactive sql monitor:
  Please read the file COPYRIGHT for copyright terms of POSTGRESQL
[PostgreSQL 6.5.0 on i586-pc-linux-gnulibc1, compiled by gcc egcs-2.91.66]

   type \? for help on slash commands
   type \q to quit
   type \g or terminate with semicolon to execute query
 You are currently connected to the database: test

test=> CREATE TABLE bug_t(word TEXT);
CREATE
test=> INSERT INTO bug_t VALUES('hello1');
INSERT 60937 1
test=> INSERT INTO bug_t VALUES('hello2');
INSERT 60938 1
test=> SELECT * FROM bug_t where word like 'hello%';
word
------
hello1
hello2
(2 rows)
test=> SELECT * FROM bug_t where word like '%hello%';
word
------
hello1
hello2
(2 rows)

No problem. This is Linux x86, 2.0.36, 6.5 current
