Two ways using PSQL:
1. Select HTML output ("\H" command) and then do a very minor amount of
post processing (details left to the reader).
2. Select "expanded" output ("\x" command), and then use SED to
post-format the output into XML:
sed -r 's:^-\[ RECORD (.*) \]-+$:</row>\n<row number="\1">:;s:([^ ]*)
+\| (.*): <\1>\2</\1>:;s:^$:</row>:;1s:</row>\n::'
There's probably a cleaner way with AWK, but the above is simple enough
(your eMail reader may break the above into separate lines at the
positions where I had a space). The last two "s" commands just handle
the first/last line cases.
The only thing the above does not handle is NULL values as distinct from
zero-length strings.
