The FAQs state "Maximum number of columns in a table? 250-1600 depending on column types".
Is there a location which gives instructions for calculating whether a number of columns of different types can be accommodated?
I have a situation where I need to load tables from another database which may theoretically contain up to 1000 columns per table and this information will determine whether I need to rebuild PostgreSQL with a larger blocksize. Splitting into multiple tables is not always an easy option.
Many thanks
Gerry
