..
> In db.drivers there is a "-p" for "print tables and exit" [1], but it

the output is correct,

GRASS> db.drivers -p
sqlite
dbf
ogr
pg

The module is to tell you about installed db DRIVERS not TABLES.
It is working fine.

AFAICT, comment is unused in GRASS 6 (???).
see lib/db/dbmi_base/dbmscap.c


here's the actual code:


db/base/drivers.c

    for (p = list; p; p = p->next) {
      fprintf(stdout, "%s", p->driverName);
      if (parms.f) fprintf(stdout, ":%s", p->comment);
      fprintf(stdout, "\n");
    }


include/dbmi.h

typedef struct _dbmscap {
    char driverName[256];   /* symbolic name for the dbms system */
    char startup[256];      /* command to run the driver */
    char comment[256];      /* comment field             */
    struct _dbmscap *next;  /* linked list               */
} dbDbmscap;
