Storing files in postgres db

Dear all,

I am intending to store the files inside the postgres DB using the
type text (all the files will be pre-encode into base64. The reason
for not using the type bytea as I encountered some undesired
format(the original file alignment can't be preserved) while
extracting the content and display iit using php).

Will it be a bad idea for storing the files in DB? the file size is
about 20 ~ 40 KB. 3K files need to be stored per day. Is there any
impact on the DB performance?

Thanks
