Best way to store arrays of simple data in PostgresQL

Question

I am creating a database where one of the 'user' tables needs to have an array of foreign keys linking to multiple rows of another table. I'm trying to figure out the best way to handle this.

user	projects
jeff	[1,2,6]
dave	[3,4]

projects	otherstuff
1	'content 1'
2	'content 2'
3	'content 3'
4	'content 4'
5	'content 5'
6	'content 6'

I guess could make a table for every user called 'user_projects' but if I have 10k users, it seems frustrating to have 10k tables with redundant rows if each some users work on the same project.

Thoughts?
