Welp, that's your problem I suspect! Postgres is going to read every
single record in your table to find the result. You need an index, and
Postgres needs to use it. If you don't have an index, add one:
create index table1_name_idx on table1(name);
After you have an index, Postgres needs to learn to use it:
vacuum verbose analyze table1;
Then re-run explain and let us know how things shake out.
