Ayuda postgresql windows!!!

Buen día!!!
Tengo un problema con postgresql en su version windows y quisiera saber si
alguien me puede dar una luz. El problema es el siguiente:
Tengo un sistema que esta llenando una tabla de la base de datos
aproximadamente en 300000 registros al día, pero pasados 3 o 4 dias la base
de datos me da problemas de lentitud y debo empezar a borrarle registros a
la tabla. La tabla tiene indices (btree y gist, pues es una tabla
geografico) y se le hace vacumm analize seguido. El otro problema se me
presento esta semana, el servicio de base de datos se cayo y ya no subio
mas. El log que me dejo fue el siguiente:
2006-11-04 20:37:16 LOG: database system was interrupted while in recovery

and you will have to use the last backup for recovery.

This application has requested the Runtime to terminate it in an unusual
way.
Please contact the application's support team for more information.
2006-11-04 20:37:16 LOG: startup process (PID 1348) was terminated by signal
