| Dear All, I have to take backup of a database as a SQL file using the pg_dump utility and I have to check the disk space before taking the backup. Hence I need to estimate the size of the pg_dump output. The size given by pg_database_size procedure and the size of file generated by pg_dump vary to a large extent. Kindly let me know how to estimate the size of the file that pg_dump generates. Note: Please bear with us for the disclaimer because it is automated in the exchange server.

I think this issue cropped up a year or two ago, and one of the suggestions was for the offender to simply put a link back to their disclaimer at the foot of their email, rather than that uber-verbose message. ---------------------------(end of broadcast)--------------------------- TIP 3: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faq |

Right. The problem is that most of the posters have no control over their footers --- it is added by their email software. -- Bruce Momjian <bruce@momjian.us> http://momjian.us EnterpriseDB http://www.enterprisedb.com + If your life is a hard drive, Christ can be your backup. + ---------------------------(end of broadcast)--------------------------- TIP 7: You can help support the PostgreSQL project by donating at http://www.postgresql.org/about/donate |

I wrote the following TOS for my personal system: https://www.potentialtech.com/cms/node/9 Excerpt of the relevant part: "If you send me email, you are granting me the unrestricted right to use the contents of that email however I see fit, unless otherwise agreed in writing beforehand. You have no rights to the privacy of any email that you send me. If I feel the need, I will forward emails to authorities or make their contents publicly available. By sending me email you consent to this policy and agree that it overrides any disclaimers or policies that may exist elsewhere." I have no idea if that's legally binding or not, but I've talked to a few associates who have some experience in law, and they all argue that email disclaimers probably aren't legally binding anyway -- so the result is undefined. Don't know if this addresses the issue or confuses it ... ? -- Bill Moran Collaborative Fusion Inc. ---------------------------(end of broadcast)--------------------------- TIP 3: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faq |

No, it's not legally binding. Agreements are only binding if both parties agree, and someone sending you email has not consented to your statement. If I send you something with a copyright mark, you'd better respect it unless you have a signed agreement granting you rights. Federal law always wins. Disclaimers are bad for two reasons. First, they're powerless. Just because Acme Corp. attaches a disclaimer doesn't mean they've absolved themselves of responsibility for the actions of their employees. Second, they're insulting to the employees. It's a big red flag saying, "We, Acme Corp., hire clowns we don't trust, and THIS person may be one of them!"

To take this back to the PG problem: it's probably true that we can ignore disclaimers as far as receiving, redistributing, and archiving mail list submissions goes. On the other hand, accepting a patch is another matter. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 4: Have you searched our list archives? http://archives.postgresql.org |

A published policy on patch submission making them fit whatever legal model is desired would avoid any and all legal issues related to legalease included with a submission. The would-be patcher's action of submission can also count as acknowledgement of the actual agreement - your agreement - if you've got the policy unambiguously and prominently displayed...
