hi all!
coding a database search program on web,
i want to have that pg to find tuples including
the string that a user inputs.

Does Postgres supply built-in function such like strstr()
in C ?

    You can use the SQL "like" operator and do something like:

select *
from table
where field like '%somestring%'

    The "%" == zero or more of any character.
