Help with command syntax?

From
Carol Walter

Greetings,

Can someone help me with the syntax for running a postgres function
from the within psql?  I need to know the size of several databases.
The postgres documentation says there is a function that will do what
I need.  The function is pg_database_size(name).  I tried select
pg_database-_size(km).  The response I get says there is no column
"km".  I think I must be using the wrong syntax, but haven't found a
reference to what the correct syntax is.

Thanks,
Carol Walter

You need to put the database name in single quotes:

select pg_database_size('km');
