SQL syntax

Hello,

I have a table containing the months of the year :

travail=> select * from mois order by id_mois;

id_mois|mois_fr |mois_en |mois_de
-------+---------+---------+---------
1|Janvier |January |Januar
2|Fevrier |February |Februar
3|Mars |March |Marz
4|Avril |April |April
5|Mai |May |Aber
6|Juin |June |Juni
7|Juillet |July |Juli
8|Aout |August |August
9|Septembre|September|September
10|Octobre |October |Oktober
11|Novembre |November |November
12|Decembre |December |Dezember
(12 rows)

And I try to obtain for one month given (for example August : 8) two
previous months, the current month, and nine next months :

id_mois|mois_fr |mois_en |mois_de
-------+---------+---------+---------
6|Juin |June |Juni
7|Juillet |July |Juli
8|Aout |August |August
9|Septembre|September|September
10|Octobre |October |Oktober
11|Novembre |November |November
12|Decembre |December |Dezember
1|Janvier |January |Januar
2|Fevrier |February |Februar
3|Mars |March |Marz
4|Avril |April |April
5|Mai |May |Aber

Do you see how making in a SQL request ?

Thank you.
