Hi everyone,
Is it possible to convert a boolean yes or no field to hold a one
letter string? For example, the strings: 's' 'f' 'p' 'e'
To start off, I just need to convert true to 's'. false will have to
be manually changed to 'f' or 'p' or 'e' as appropriate.
Why not an enum field?:

I thought enum was Considered Harmful because of the difficulty in
altering the enums?
The difficulty is removing a value:
https://www.postgresql.org/docs/11/sql-altertype.html
Otherwise I see equal difficulty in pretending that s, f, p and e are a
boolean choice.
