That is cetainly odd. It is using this C code:
if (GET_MAJOR_VERSION(old_cluster.major_version) < 803)
pg_log(PG_FATAL, "This utility can only upgrade from PostgreSQL version 8.3 and later.\n");
which is assigned from this function:
get_major_server_version(ClusterInfo *cluster)
{
FILE *version_fd;
char ver_filename[MAXPGPATH];
int integer_version = 0;
int fractional_version = 0;
snprintf(ver_filename, sizeof(ver_filename), "%s/PG_VERSION",
cluster->pgdata);
if ((version_fd = fopen(ver_filename, "r")) == NULL)
return 0;
if (fscanf(version_fd, "%63s", cluster->major_version_str) == 0 ||
sscanf(cluster->major_version_str, "%d.%d", &integer_version,
&fractional_version) != 2)
pg_log(PG_FATAL, "could not get version from %s\n", cluster->pgdata);
fclose(version_fd);
return (100 * integer_version + fractional_version) * 100;
}
Can you show me what is in the PG_VERSION file in the old cluster? It
should be "9.1".
