I guess the problem here that other columns also could contain space separated values like e.g. comm

I tried this ./sqlsh select distinct \`user\` from ps for the branch for this PR
and the output is

6.9
13.3
0.0
0.1
1.0
0.2
1.1
0.3
1.2
69.7
39.5
0.4
0.5
0.6
0.7
108
4.4
0.8
1.8
35.8
0.9

while for main same query is

message+
serg
avahi
lp
kernoops
root
rtkit
syslog
systemd+
colord

after some checks I noticed that command could also contain space separated values and probably this is the reason...

Can we add some tests to illustrate the jira case?
