Fix punctuation errors in PostgreSQL documentation

Hi,

I am a member of the project translating PostgreSQL documentation into Japanese.
For the translation, I check the number of sentences by periods.
I found some issues in the original English documentation that I
believe need to be corrected.

Could you please review the attached patch file?

Best regards,
