Here are some my comments:

The document of psql needs to be updated. At least the description of new option
this patch adds needs to be added into the document.

+    printf(_("  --help-variables         list of available
configuration variables (options), then exit\n"));

We should get rid of "of" from the message, or add "show" in front of "list of"?

+    printf(_("  ECHO               write all input lines to standard
output\n"));

This message seems not to be correct when ECHO=queries is set.

+    printf(_("  COMP_KEYWORD_CASE  determines which letter case to
use when completing an SQL key word\n"));
+    printf(_("  DBNAME             name of currently connected database\n"));
+    printf(_("  ECHO               write all input lines to standard
output\n"));

I found that some help message line uses a normal form of a verb, but
other does not.
We should standardize them?

+    printf(_("  PROMPT1, PROMPT2, PROMPT3  specify the psql prompt\n"));

When the option name field is long, we should add a new line just
after the name field
and align the starting position of the option explanation field. That is,
for example, the above should be

printf(_("  PROMPT1, PROMPT2, PROMPT3\n"
             "                     specify the psql prompt\n"));

+    printf(_("  ON_ERROR_ROLLBACK  when on, ROLLBACK on error\n"));

This message seems incorrect to me. When this option is on and an error occurs
in transaction, transaction continues rather than ROLLBACK occurs, IIUC.
I did not check whole help messages yet, but ISTM some messages are not correct.
It's better to check them again.

+    printf(_("  PSQL_RC            alternative location of the user's
.psqlrc file\n"));

Typo: PSQL_RC should be PSQLRC

+    printf(_("  PGDATABASE         same as the dbname connection
parameter\n"));
+    printf(_("  PGHOST             same as the host connection parameter\n"));
+        printf(_("  PGPORT             same as the port connection
parameter\n"));
+    printf(_("  PGUSER             same as the user connection parameter\n"));
+    printf(_("  PGPASSWORD         possibility to set password (not
recommended)\n"));
+    printf(_("  PGPASSFILE         password file (default ~/.pgpass)\n"));

I don't think that psql needs to display the help messages of even environment
variables supported by libpq.


Main reason is a PGPASSWORD -- it is probably most used env variable with psql

PGPASSWORD=****** psql is very often used pattern
