I found it annoying that sql_help.c contains a literal parameter as a
translatable string.
The cause is that create_help.pl treats <literal>match</> as a
replaceable. The attached excludes literals from translatable strings.
By a quick look it seems to me that the "match" in "COPY.. HEADER
match" is the first and only instance of a literal parameter as of
PG15.
regards.
