Hi All, While working on partition-wise join, I had to examine Relids objects many times. Printing the Bitmapset::words[] in binary format and then inferring the relids takes time and is error prone. Instead I wrote a function bms_to_char() which allocates a StringInfo, calls outBitmapset() to decode Bitmapset as a set of integers and returns the string. In order to examine a Relids object all one has to do is execute 'p bms_to_char(bms_object) under gdb.
Can we not do this as gdb macros? My knowledge is rusty in this area and lately I'm using LVM debugger (which probably does not have something equivalent), but I believe gdb allows you to write useful macros. As a bonus, you can then use them even for inspecting core files.
