11 | # Version 6.5.3-2 Lamar Owen |
---|
12 | # Added code to determine if PGDATA exists, whether it is current version |
---|
13 | # or not, and initdb if no PGDATA (initdb will not overwrite a database). |
---|
14 | |
---|
15 | # Version 7.0 Lamar Owen |
---|
16 | # Added logging code |
---|
17 | # Changed PGDATA. |
---|
18 | # |
---|
19 | |
---|
20 | # Version 7.0.2 Trond Eivind Glomsrd <teg@redhat.com> |
---|
21 | # use functions, add conditional restart |
---|
22 | |
---|
23 | # Version 7.0.3 Lamar Owen <lamar@postgresql.org> |
---|
24 | # Check for the existence of functions before blindly using them |
---|
25 | # in particular -- check for success () and failure () before using. |
---|
26 | # More Cross-distribution support -- PGVERSION variable, and docdir checks. |
---|
27 | |
---|
28 | # Version 7.1 Release Candidate Lamar Owen <lamar@postgresql.org> |
---|
29 | # initdb parameters have changed. |
---|
30 | |
---|
31 | # Version 7.1.2 Trond Eivind Glomsrd <teg@redhat.com> |
---|
32 | # Specify shell for su |
---|
33 | # Handle stop better - kill unwanted output, make it wait until the database is ready |
---|
34 | # Handle locales slightly differently - always using "C" isn't a valid option |
---|
35 | # Kill output from database initialization |
---|
36 | # Mark messages for translation |
---|
37 | |
---|
38 | # Version 7.1.2-2.PGDG Lamar Owen <lamar.owen@wgcr.org> |
---|
39 | # sync up. |
---|
40 | # Karl's fixes for some quoting issues. |

46 | # reload from Peter E. |

47 | # Eliminate the pidof postmaster test in stop -- we're using pg_ctl so we don't need pidof. |
