But a right-aligning string output routine needs to be used.
cdrs=> select val, tc, '"'||tc||'"' as quoted,
'"'||regexp_replace(tc,'\.$',' ')||'"' as replaced from (select val,
to_char(val::decimal(6,2),'FM999,990D99') as tc from (values
(1234),(1.05),(0)) as v(val)) as w;
val | tc | quoted | replaced
------+--------+----------+------------
1234 | 1,234. | "1,234." | "1,234 "
1.05 | 1.05 | "1.05" | "1.05"
0 | 0. | "0." | "0 "
(3 rows)
Summarising, any combination can be easily done with a single round of replace.
