You didn't show us any \timing. The 94.109 ms figure is all server-side.
As an example:
regression=# \timing
Timing is on.
regression=# explain analyze select * from tenk1;
QUERY PLAN
-------------------------------------------------------------------------------------------------------------
Seq Scan on tenk1 (cost=0.00..458.00 rows=10000 width=244) (actual
time=0.050..149.615 rows=10000 loops=1)
Total runtime: 188.518 ms
(2 rows)
Time: 210.885 ms
regression=#
Here, 188.5 is at the server, 210.8 is at the client. The difference is
not all network delay, either --- parse/plan overhead is in there too.
