Here's the patch I promised over on HACKERS - it alters the implementation of '\e' history tracking for systems that have a readline compatability library without replace_history_entry. I fall back to pushing the query onto the history stack after the \e, rather than replacing it. The patch adds one more place to look for readline headers, and a test for replace_history_entry.

Here's some changes I made last night to psql's common.c (as found in 7.3.2). It removes some code duplication and #ifdeffing, and some unstructured ugliness such as tacky breaks and an unneeded continue. Breaks up a large function into smaller functions and reduces required nesting levels, and kills a variable or two. Jeroen T. Vermeulen 2003-03-20 07:00:12 +01:00

Another pgindent run. Fixes enum indenting, and improves #endif spacing. Also adds space for one-line comments. 2001-10-28 07:26:15 +01:00
