Inheritence and Integrity

I am creating a database that will keep track of several different types 
of 'events'. I am toying with the idea of making a base 'class' table 
for the tables because a lot of the information will be the same (also 
there will probably be times I just need to get the basic information 
about events regardless of their type). My question is: will triggers 
and rules on the parent table fire when I insert data in the child 
tables? Are there any other potential pitfalls?

Thank you,

P.S. Here is a simplified example of my schema:

CREATE TABLE parenttable (recordid SERIAL PRIMARY KEY,recordname text
);

CREATE TABLE childtablea (afield int4
) INHERITS parenttable;

CREATE TABLE childtableb (bfield text
) INHERITS parenttable;

CREATE TABLE extrainfo (extrainfoid SERIAL PRIMARY KEY,record_fkey int4 NOT NULL REFERENCES
parenttable(recordid),extrainfotexttext
 
);
